How to test:

• run portal
• deploy petra client
• deploy app that uses petra (it is important that app activates petra json ws client with good connection parameters)
• once all set push your machine in sleep mode
• once one is sure machine is hibernated, wake up machine
• make sure portal is available at localhost:8080
• perform graceful shutdown

check log in LIFERAY_HOME/osgi/state/ - there should not be NullPointerError that refers
