I have an application with Spring Integration that queues incoming messages in a PriorityChannel which are persisted using a messageStore using MongoDbChannelMessageStore implementation. Currently we are under Springboot 2.1.3 version. And we make all the necessary changes to go to 2.5.4 version. Many changes in build.gradle, AWS package refactor etc, etc... no problem with this and everything works as expected.
The specific problem is that if I want to upgrade having stored incoming messages with the older version in production, when the application with the new version continues to process this load the following error occurrs. Seems to be a convertion from spring integration that goes wrong. Any advice please?

Yeah... Looks like some org.springframework.util.LinkedCaseInsensitiveMap class internal state has been changed in between and its previously serialized version is not compatible with what a new app is expecting.
You probably need to implement and Adapter application which would be based on an old version of Spring Boot. Offloads those messages, removes (or convert) the header with that org.springframework.util.MimeType value and serializes them back to the queue for a new app.
I don't think it really have a significant value to really store the whole org.springframework.util.MimeType, but not just its plain string representation...

I submitted my jar with dependencies to spark using spark-submit. In main method of my jar I want to create HttpAsyncCliens instance and execute some request (apache http async client library):
val httpClient = HttpAsyncClients.custom.setMaxConnTotal(10).setMaxConnPerRoute(10).build
httpClient.start()
httpClient.execute(new HttpGet("https://google.com"), new FutureCallback[HttpResponse] {
/* callbacks */
})
It throws exceptions:

It seems like there is no http-core dependency in my jar but I can call this method (org.apache.http.util.Asserts.check(ZLjava/lang/String;Ljava/lang/Object;)V) in code before or after http client creation and request:
org.apache.http.util.Asserts.check(true, "test", "test2") // it produces no exception
val httpClient = HttpAsyncClients.custom.setMaxConnTotal(10).setMaxConnPerRoute(10).build
httpClient.start()
httpClient.execute(new HttpGet("https://google.com"), new FutureCallback[HttpResponse] {
/* callbacks */
}) // it produces exception
Why I got NoSuchMethodError if I can call this method from same classpath in code?
Apache httpasyncclient v4.1
The solution here is to sync up with the version of httpcomponents.httpcore that is in the immediate classpath of spark. For version 1.6 the version is 4.0.1.
You will have to unzip the spark jar to view the META-INF, etc. After some detective work things will be alright!
I have created an embedded Jetty application which utilizes Jersey in order to implement several RESTful services. I am using some standard code as described here in Stack Overflow as well as other websites:
public static void main(String[] args)
{
Server server = new Server(8080);
ServletContextHandler ctx = new ServletContextHandler(
ServletContextHandler.SESSIONS);
ctx.setContextPath("/");
ServletHolder holder = ctx.addServlet(
"org.glassfish.jersey.servlet.ServletContainer.class", "/*");
holder.setInitOrder(0);
holder.setInitParameter("jersey.config.server.provider.classnames",
RestfulClass.class.getCanonicalName());
server.setHandler(ctx);
try
{
server.start();
server.join();
}
catch(Exception exe)
{
exe.printStackTrace();
}
}
I've used all the recommended jar files, and several other jar files that the various blogs and sites failed to mention. When running the Jetty application, I get the following exception:
java.lang.ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer.class

It is the "UnavailableException" that I do not understand. The ServletContainer class is actually in one of the Jar files (in jersey-container-servlet-core.jar, to be precise), but for some reason it is identified as "unavailable". This is causing a class that is actually in a referenced Jar file to be "not found"!
Can anyone tell me what is causing this UnavailableException and (more importantly) how I can prevent it from being thrown?
Someone please advise...
ServletHolder holder = ctx.addServlet(
"org.glassfish.jersey.servlet.ServletContainer.class", "/*");
You are using a String for the class name. When doing this, you don't use the .class suffix. That at only when you want to get the actual Class object. You have two options
Remove the .class from the String
ServletHolder holder = ctx.addServlet(
"org.glassfish.jersey.servlet.ServletContainer", "/*");
Remove the "" (double quotes) and just use the Class object1.
ServletHolder holder = ctx.addServlet(
org.glassfish.jersey.servlet.ServletContainer.class, "/*");

I am trying to send an email from my code that runs on Tomee 1.6
I have the following entry in the tomee.xml file.

</Resource>
I have an ejb with the following declaration.
#Resource(name = "abc_mail")//, type = javax.mail.Session.class)
Session abcMailSession;
The code for sending the email is the following.
public void sendMessage(String addressTo, String subject, String messageText) {
try {
Message message = new MimeMessage(abcMailSession);
message.setFrom(new InternetAddress("abc#xyz.com"));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(addressTo));
message.setSubject(subject);
message.setText(messageText);
Transport.send(message);
logger.info("Message sent successfully.");
} catch (MessagingException e) {
throw new RuntimeException(e);
}
}
When calling this method I get the following error.

Why do I get this error? I am not able to figure out the first line in the stack trace.
I have now solved this. The error occurs because the same class is being loaded by two different classloaders (tomcat and openejb ones), the class in question is javax.mail.Session
I added the following property to tomee's system.properties file
openejb.classloader.forced-skip=javax.mail
What this does it prevents openejb classloader from loading the javax.mail classes and therefore only tomcat classloader loads all the relevant classes required for sending email.
I'm writing a web service layer using Resteasy and I tried to configure infinispan as a server side response cache, as described here: http://docs.jboss.org/resteasy/docs/3.0.1.Final/userguide/html_single/index.html#server_cache
Because this layer is stateless and might be deployed on a multitude of nodes on heroku, I wanted to use a mongodb cache loader to store the cache data. This way, the cache would be synched between all nodes.
However, when starting my server in my local machine, I get the following error:
org.infinispan.CacheException: Unable to start cache loaders (full stack trace at the end of this message)
Here's my declared dependencies:
compile 'org.jboss.resteasy:resteasy-jaxrs:3.0.1.Final'
compile 'org.jboss.resteasy:resteasy-client:3.0.1.Final'
compile 'org.jboss.resteasy:resteasy-spring:3.0.1.Final'
compile 'org.jboss.resteasy:resteasy-cache-core:3.0.1.Final'
compile 'org.infinispan:infinispan-cachestore-mongodb:5.3.0.Final'
(It's strange that the org.infinispan:infinispan-cachestore-mongodb:5.3.0.Final jar includes almost all the classes also present in org.jboss.resteasy:resteasy-cache-core:3.0.1.Final. I wonder if that's what is causing the problem. I played a lot with the dependency graph trying to exclude the duplicates to a point where I built my own mongo cache loader jar with only the pertinent classes, but doing that or removing the core jar and leaving only the mongo cache loader jar thrown an exception like Unexpected element '{urn:infinispan:config:5.3}infinispan'
)
I also configured infinispan.xml following the documentation on the site: https://docs.jboss.org/author/display/ISPN/Cache+Loaders+and+Stores#CacheLoadersandStores-MongoDBcacheloader
<?xml version="1.0" encoding="UTF-8"?>

</mongodbStore>
</loaders>
</namedCache>
</infinispan>
I'm not sure if it's a version conflict which is causing the issue or if it is a bug on the mongodb cache laoder. I'm also not sure if there's an additional step I need to perform to register the mongo db loader within infospan config. On another thread, someone had the same error when creating a custom loader because he didn't implement the CacheLoaderConfig.getCacheLoaderClassName(). I fussed around the mongo db loader source code in github but couldn't find any reference to this method. Here's the thread for reference: https://community.jboss.org/thread/218305
Any help would be appreciated. Let me know if you need more info.

UPDATE
I step traced the source code for Infinispan and I narrowed down the error to this method on class org.infinispan.loaders.CacheLoaderManagerImpl. The cfg instance is of type org.infinispan.loaders.mongodb.MongoDBCacheStoreConfig, which interestingly I can't find on any library in Eclipse's classpath. So I assume this class is created at runtime? The NPE error is reported because cfg.getCacheLoaderClassName() returns null on the very 1st line.
CacheLoader createCacheLoader(CacheLoaderConfig cfg, AdvancedCache<Object, Object> cache) throws Exception {
CacheLoader tmpLoader = (CacheLoader) Util.getInstance(cfg.getCacheLoaderClassName(), cache.getClassLoader());
if (tmpLoader != null) {
if (cfg instanceof CacheStoreConfig) {
CacheStore tmpStore = (CacheStore) tmpLoader;
// async?
CacheStoreConfig cfg2 = (CacheStoreConfig) cfg;
if (cfg2.getAsyncStoreConfig().isEnabled()) {
tmpStore = createAsyncStore(tmpStore, cfg2);
tmpLoader = tmpStore;
}
// read only?
if (cfg2.isIgnoreModifications()) {
tmpStore = new ReadOnlyStore(tmpStore);
tmpLoader = tmpStore;
}
// singleton?
SingletonStoreConfig ssc = cfg2.getSingletonStoreConfig();
if (ssc != null && ssc.isSingletonStoreEnabled()) {
tmpStore = new SingletonStore(tmpStore, cache, ssc);
tmpLoader = tmpStore;
}
}
// load props
tmpLoader.init(cfg, cache, m);
}
return tmpLoader;
}
When trying to initialize hibernate from configuration file, I get NullPointerException ..
Root cause is shown as
Caused by: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: java.lang.NullPointerException (Caused by java.lang.NullPointerException) (Caused by org.apache.commons.logging.LogConfigurationException: java.lang.NullPointerException (Caused by java.lang.NullPointerException))
at org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryImpl.java:543)
I have all the logging related jars and properties files in class path.
My hibernate initialization code is :
private static final SessionFactory sessionFactory;
private static final ThreadLocal<Session> hibernateSession=new ThreadLocal<Session>();
static{
try{
sessionFactory=new Configuration().configure("llhs_hibernate.cfg.xml").buildSessionFactory();
System.out.println("done");
}catch (HibernateException he){
he.printStackTrace();
throw new ExceptionInInitializerError(he);
}catch (Exception e){
e.printStackTrace();
throw new ExceptionInInitializerError(e);
}
Simple java classes does not complain about log related error, for example following java class does not complain ..It properly initializes and writes to logs folder
public class MetadataService implements Serializable {
private static final Logger logger = LogManager.getLogger(MetadataService.class);
private static final long serialVersionUID = 1L;
public MetaData getMetaData(){
logger.info("Info");
try {
//some code here
} catch (Exception e1) {
logger.error("Error");
}
return metaData;
}
Since it works for stand alone Java class and not for class doing hibernate initialization --I am more perplexed ..Any pointer? Detailed trace
java.lang.ExceptionInInitializerError

There is alignment issue while posting trace, sorry abt that, not able to correct that one..
Finally, I was able to solve this. As later guessed it turned out to be an eclipse configuration. In eclipse 3.7, code name indigo, the way libs were being added to the classpath caused this issue ..
First way:
Debug Configurations->classpath->bootstarp entries, if Add libs added by selecting "Add Jars" options, THIS DOES NOT Work.
Correct WAY:
Define a classpath variable from window->preferences->java->buildpath->classpath variable, say HIBERNATE_LIBS and point it ti libs folder
Now, got to Debug Configurations->classpath->bootstarp entries, select "Advanced option" and add the class path variable. This FIXED the issue.
I guess this is specific to 3.7, as I upgraded the eclipse version and started getting this issue, First way still works in eclipse 3.2
