[#PETALSDISTRIB-2] Memory-leak on installation/uninstallation and deployment/undeployment - Petals Link JIRA

Description:

When installing/uninstalling components and deploying/undeploying services, a memory leak occurs. And after some iteration, the Petals ESB container crashes because of an exception OutOfMemory of the PermGen space of the JVM

Depends

This issue depends on:
PETALSSEPOJO-15 Memory-leak because service-unit is not unreferenced when shutdowning it if an error occurs during its stop
~~PETALSCDK-83~~ Memory leak because the JBIAcceptorManager.acceptorPool is not freed
~~PETALSDISTRIB-334~~ Upgrade Apache Commons Pool to the version 2.6.0
~~PETALSCDK-76~~ Memory-leak because runtime configuration listeners are not unregistered
~~PETALSCDK-77~~ Memory-leak because utility singletons are not freed
~~PETALSESBCONT-178~~ The RuntimeConfigurationNotifier mbean is not freed when stopping/shutdowning/uninstalling a component, if JVisualVM is connected to the container
~~PETALSBCSOAP-110~~ Memory-leak when uninstalling the BC SOAP because the SOAP engine is not correctly stopped
~~PETALSCDK-80~~ Memory leak because resources of JBIBuilderDescriptor resources are not freed
~~PETALSCDK-82~~ Memory leak because of not static inner classes into the JBIProcessorManager
~~PETALSCDK-85~~ Memory leak because the ThreadGroup of JBIAcceptor is not freed
~~PETALSBCSOAP-113~~ Memory-leak because pools of service clients are not freed
~~PETALSBCSOAP-114~~ Memory-leak because static resources of class Marshaller are not freed
~~PETALSBCSOAP-115~~ Memory leak because of the Jetty logger
~~PETALSCDK-96~~ Memory leak because of a not static inner classe into the AsyncMessageManager
