RE: Exception when reloading my EAR / linked with pool of session bean ?

To be more precise, I noticed this when I stop Jonas, there is a kind of warning :

 

"WebappClassLoader.clearReferencesThreads : The web application [/OrangeOpenCloud] appears to have started a thread named [WorkThread-1/61] but has failed to stop it. This is very likely to create a memory leak."

 

Maybe it is the origin of the problem ?

Objet : [jonas] Exception when reloading my EAR / linked with pool of session bean ?

 

Hello there,

 

When I redeploy my EAR on Jonas (5.2 version) I noticed this exception (not every time) : 

 

AbsTransactionInterceptor.handleContextContainerTransaction : Exception (not application exception) in business method

javax.ejb.EJBException: java.lang.IllegalArgumentException: Cannot get element in the pool at org.ow2.easybeans.proxy.client.AbsInvocationHandler.handleThrowable(AbsInvocationHandler.java:176)

 

It seems to be linked with the loading of a Timer session Bean and the associated pool :

Please can you help me ? Is there a setting in Jonas to change to increase session bean pool ?

 

Thanks a lot.
