public class PessimisticLockInterceptor
extends PostProcessingCommandInterceptor

An interceptor that handles locking. When a TX is associated, we register for TX completion and unlock the locks acquired within the scope of the TX. When no TX is present, we keep track of the locks acquired during the current method and unlock when the method returns.
