Hi Ashish,
there is two possibilities:
(1) There is a thread pool or object in GlassFish that store the
ContextClassloader and try to re-use it. The ContextClassLoader of a web
application is always a WebappClassloader, and that classloader is
marked dead when the application is undeployed. In 9.0, we fixed a bug
in the ORB thread pool related to that problem. This time I suspect the
component that create it is:
> at com.sun.enterprise.instance.SerializedDescriptorHelper.storeSerializedDescriptor(SerializedDescriptorHelper.java:239)
> at com.sun.enterprise.instance.SerializedDescriptorHelper.store(SerializedDescriptorHelper.java:143)
> at com.sun.enterprise.instance.SerializedDescriptorHelper.store(SerializedDescriptorHelper.java:123)
> at com.sun.enterprise.instance.BaseManager.saveAppDescriptor(BaseManager.java:684)
> at com.sun.enterprise.deployment.backend.EJBCompiler.preDeployModule(EJBCompiler.java:352)
(2) Your application is holding the classloader. Are you loading classes
using the ContextClassloader and try to re-use that Classloader?
If your application doesn't use or store the ContextClassLoader, that
means one component in GlassFish is doing it. Now to find the component
that does it is far from simple. Last time I've instrumented the JDK
classes to find which component was doing that. Just file a bug if you
think your application is not storing the classloader.
Thanks
