Both my client and server are running on adopopenjdk 11.0.9.101.
I'm running this on Windows 10 Home edition.
My client tries to connect to the management REST API. (All of this has worked on Java 8 in the past)
On the server side I have a standard Wildfly 19 server with some mail smtp properties .
<outbound-socket-binding name="mail-smtp">
<remote-destination host="some.smtp.server" port="465"/>
</outbound-socket-binding>
A management user was created called "admin".
The client has a fairly small main method which tries to read these properties.
HttpAuthenticationFeature feature = HttpAuthenticationFeature.digest("admin", "admin");
Client client = ClientBuilder.newClient();
client.register(feature);
WebTarget target = client.target("http://localhost:9990/management")
.path("/socket-binding-group/standard-sockets/remote-destination-outbound-socket-binding/mail-smtp")
.queryParam("operation", "resource");
Response r = target
.request(MediaType.APPLICATION_JSON)
.get();
Map<String, Object> smtpResponse = r.readEntity(new GenericType<HashMap<String, Object>>() { });
System.out.println(smtpResponse);
This results on the server side in the following output:

I faced a problem with camel REST routes when I switched from camel version 3.5.0 to version 3.8.0.
In the version 3.8.0 all routes from the REST service are generated twice! So at start of the camel context the exception is thrown:
Failed to start route route7 because of Multiple consumers for the same endpoint is not allowed: jetty:http://0.0.0.0:6060/start?httpMethodRestrict=GET
In detail:
I have a simple RouteBuilder to generate REST routes:
#Component
public class RestInterface extends RouteBuilder {
#Override
public void configure() throws Exception {
restConfiguration()
.component("jetty")
.host(urlInfo.getHost())
.port(urlInfo.getPort())
.bindingMode(RestBindingMode.json)
.dataFormatProperty("prettyPrint", "true")
.clientRequestValidation(true);
rest("/")
.get("/start").outType(RepositoryPackageInfo.class).to("direct:start")
.get("/stop").outType(RepositoryPackageInfo.class).to("direct:stop");
// ...
}
}
When I start this code with camel 3.8.0 I get following console output:
...

...
If I run the same code with camel 3.5.0, the application starts without exceptions, and camel has only 38 routes:

Check if configure method on your RestInterface RouteBuilder is getting called more than once. Multiple calls cause duplicate RouteDefinitions to be added to the RouteBuilder instance which can lead to this error.
One way to solve this is to use boolean value in your RouteBuilder to check if configure method has already been called. Then use this value to early out or to throw an exception.
boolean isConfigured = false;
#Override
public void configure() throws Exception {
if(isConfigured){
return;
}
// Configure routes
isConfigured = true;
}
Encountered similar problem with Camel 2.x running in Karaf + OSGi where modifying config file lead to same error.
Basically configuring CamelContext service caused it to restart while the RouteBuilder services it referenced kept their state leading to situation where their configure method got called the second time leading to same error.
I have created JPA Spring boot application which is working properly in my local environment, however, while deploying it to Java Liberty Cloud Foundary app in IBM Bluemix with following error:
Local IDE: Eclipse Oxygen
when I run this application on my local IDE, it accessed cloud Db Compose for MySQL and give result as expected.
http://localhost:8080/users/all
Deployment in IBM Bluemix, it's give an error message

log4j-1.2.17.jar
slf4j-api-1.7.7.jar
slf4j-simple-1.6.1.jar
I have added those jar files after checking the exception messages in the console. But I couldn't understand this exception.
Can anyone please help me fixing this.
This is my driver class.
Configuration conf = new Configuration();
// Creating a job
Job job = Job.getInstance(conf,"WordCountDriverClass");
job.setJarByClass(WordCountDriverClass.class);
job.setMapperClass(WordCountMapper.class);
job.setReducerClass(WordCountReducer.class);
job.setNumReduceTasks(2);
job.setInputFormatClass(KeyValueTextInputFormat.class);
job.setOutputKeyClass(Text.class);
job.setOutputValueClass(IntWritable.class);
FileInputFormat.addInputPath(job, new Path("inputfiles"));
FileOutputFormat.setOutputPath(job, new Path("outputfiles"));
job.waitForCompletion(true);
Looks like you are running the wordcount example, what it requires are 1.2.1 hadoop-core and 2.2.0 hadoop-common. If you use Maven instead, the config should be as simple as
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-core</artifactId>
<version>1.2.1</version>
</dependency>
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-common</artifactId>
<version>2.2.0</version>
</dependency>
