      Description

      Hello,
      Reviewing TransactionUtil code, I have seen 2 problems:

      • internalBegin is uselessly synchronized , since it is a static method it is a very big useless Contention Point since not unthread safe instance variable is used
      • debugResources is true which creates a DebugXAResource (that creates an Exception) , it should be false and made an option for debuging

      These 2 modifications have been in our production for a while and we noticed CPU reduction and no more contention on TransactionUtil#begin
