1.org.apache.axis2.description.AxisService#releaseSchemaList() is called when a process is undeployed.
If many processes are deployed, much heap memory was needed.
Should not releaseSchemaList() be called after BindingContextImpl#createService()?
2.org.apache.axis2.wsdl.util.WSDLWrapperBasicImpl is used as a default implementation of WSDLWrapperImpl.
I think WSDLWrapperReloadImpl is better if there are many processes,
but I can't configure axis2.xml(reduceWSDLMemoryCache,reduceWSDLMemoryType).
Please teach me to configure axis2 to use WSDLWrapperReloadImpl.
3. org.apache.ode.store.DeploymentUnitDir#getDocRegistry() loads WSDL definitions,
and keeps them in heap memory with each process.
_docRegistry should be set "null" when the process is dehydrated.
