Re: [emf-dev] OOM Metaspace


Please us the forum to ask question.   Using -Dorg.eclipse.emf.common.util.ReferenceClearingQueue=false you can disable the creation of the thread.

we develop and host a RAP e4 application on the JBoss EAP 7 and experience an java.lang.OutOfMemoryError: Metaspace after some redeployments of the application into the JBoss. An analysis if a heap dump shows that per deployment one thread org.eclipse.emf.common.util.CommonUtil$1ReferenceClearingQueuePollingThread EMF Reference Cleaner is created. This keeps the classloaders and its classes alive which later results in the OOM. 

Is it somehow possible to stop this thread when the application is undeployed?

Thanks for your help.
