Lukas Vasek commented on CXF-6852:
----------------------------------
Ok problem is following:
JaxWsDynamicClientFactory.createClient creates new ClassLoader.
But this ClassLoader is never closed.
Simple solution which worked for me should be to add to destroy() method
ClassLoader cl = Thread.currentThread().getContextClassLoader();
ClassLoader parent = cl.getParent();
Thread.currentThread().setContextClassLoader(parent);
cl = null;
a good solution could be to implement Autocloseable and inside it call
destroy() to be backward compatible.

> Hello,
> As mentioned in this issue
> http://stackoverflow.com/questions/36307555/correct-java-8-setup-for-class-unloading-metaspace-cleanup-cxf-issue
> we are getting OOM exceptions while generating dynamic clients. Problem is
> that each new generated client creates new URLClassLoader which consumes
> memory. I don't know if this is bug in CXF or it's more related to JVM setup.
> I would greatly appreciate any help.
> Thanks
