JPAService.destroy() issue

[bowen zhang]

Hi Mohammad,
I saw you wrote the line "factory.close()" in the destroy method of 
JPAService.java. I've seen some issues of this line throwing 
invalidStateException while there is active transaction happening, 
particularly on Windows. Can you tell me how you make sure there is no 
active transaction when shutting down oozie? Should this line be 
deleted?
Thanks,Bowen
