Starting Eclipse on AIX throws java/lang/OutOfMemoryError - eclipse

I've installed the Eclipse (eclipse-SDK-3.6.2-aix-gtk-ppc64.zip) on an AIX instance. Initially it appeared to be starting but buttons would just stop working. I eventually tracked this down to Eclipse throwing the following exception:

I have changed the -Xms and -Xmx values to different settings to no avail. Analyzing the corresponding thread dump shows that 99% of the memory in the VM is available.
Am I missing something obvious in setting this up?

I would try setting the -Xss and -Xmso option to set the internal/OS thread stack size. Its a nonstandard option on IBM's JVM.

After various attempts at editing the eclipse.ini file, the only reliable way I can currently start it with is by passing the -vm parameter in the startup as follow:
./eclipse -vm /Websphere/java/bin/java -vmargs -Xmx1024M &

Updating Java Heap size while deploying/installing keycloak using bitnami/keycloak

I keep getting a OutOfMemoryError while deploying/installing keycloak using bitnami/keycloak in a Kubernetes pod.

I suspect it could be because of the Java Heap size. Please correct me if I am wrong.
I have checked the resources allocated to the machine; everything looks fine. The question is how do I update the heap size in value.yaml file? Is JAVA_OPTS_APPEND in https://github.com/bitnami/charts/blob/main/bitnami/keycloak/templates/configmap-env-vars.yaml is the env variable to be overridden?
If anybody has an example, please share.

Custom class loader wtih Infinispan 9.4.x

We have been using old version of infinispan and wildfly ( 10.x and infinispan 6.x ). The cache has been used as embedded cache, e.g it was started from the application code ( which was actually the wildfly module ).Whenever cache was created in clustered mode the code created a Decorated Cache with specific class loader which allowed to handle remote data transfer and provided all the required classes.
In inifinspan 9.4.x the with(ClassLoader) is deprecated on both AdvancedCache and DecoratedCache and while checking the code we have found that it does nothing.
As result when the cache item is stored and sent to remote node remote exception is occuring (java.lang.ClassNotFoundException)
15:32:45,028 ERROR [org.infinispan.interceptors.impl.InvocationContextInterceptor] (jgroups-10,ip-10-0-0-82-23088) ISPN000136: Error executing command PrepareCommand on Cache 'ra-data-SipRA'

Source code shows that global configuration is storing class loader now and it is provided from wildfly. Is there any way to provide the custom class loader for infinispan 9.x or at least define which one to use on remote operation handling

How can i solve java.lang.IllegalStateException: Illegal access:?

I am using Eclipse to develope a webapp. Everything was working fine, but sometimes when I tried to publist->start my server, I received the following error:
Oct 03, 2019 6:52:55 PM org.apache.catalina.loader.WebappClassLoaderBase checkStateForResourceLoading
INFO: Illegal access: this web application instance has been stopped already. Could not load []. The following stack trace is thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access.

For the first few times, I just restarted the server, and it was working fine, but now even a restart doesent solve the problem. I read about it online, and some sources mentioned that it might be a thread management issue, but I couldn't get further than that. Can anybody please provide some info? Thanks.
The mysql driver is trying to clean-up on web application shutdown which is good. Unfortunately it is trying to load additional classes to perform this clean-up and - since the web application is shutting down - class loading is no longer available. Ideally, the driver would load all the classes it needed to clean-up when it firsts loads - that would avoid this issue.
If you can figure out which classes it is trying to load - a check of the driver source code should show you which - then you should be able to load them yourself on application start in, for example, a ServletContextListener.
If you created any Entity class and forgot to give ID to any specific column then also this problem occurs. So assign #ID to any column and run again. your issue will resolve.

GWT development mode issue

UPDATE
In the ProcessExplorer I can see that the JVM process hosting Jetty has an open handle to the file so this is probably the reason why the other JVM (hosting the dev mode) can't write to it. Any way to work it around?
It seems that two (open/close) (open/close) rutines over the same file happening too soon one after another causes this... Some developers suggest to call the gc. Check for closing correctly every i/o operation. Not to perform complete (open,loop(writes),close) too soon. It seems that when one operation it is going to be finished while the second request arrives and that throws the problem.
I found the solution on this page:
http://docs.codehaus.org/display/JETTY/Files+locked+on+Windows
EDIT:
The above URL is dead now.
Now it's quite easy to find the solution in Jetty's wiki:
Jetty provides a configuration switch in the webdefault.xml file for
the DefaultServlet that enables or disables the use of memory-mapped
files. If you are running on Windows and are having file-locking
problems, you should set this switch to disable memory-mapped file
buffers.
The default webdefault.xml file is in the lib/jetty.jar at
org/eclipse/jetty/webapp/webdefault.xml. Extract it to a convenient
disk location and edit it to change useFileMappedBuffer to false.
