PI15809: eXtreme Scale creates two ORB thread pools during initialization.

APAR status

• Closed as program error.

Error description

• eXtreme Scale proceses can get OutOfMemoryError errors related
  to too many threads when eXtreme Scale initializes the ORB
  used. This problem does not exist when running in a WebSphere
  Application Server process since the WebSphere Application
  Server runtime initializes the ORB.

  ****************************************************************
  eXtreme Scale initialized the ORB in such a way that the ORB
  created
  its
  default thread pool and
  then waited for eXtreme Scale to replace that thread pool with
  the
  one that it created. The initialization logic was updated to
  correctly cause the ORB to only use the eXtreme Scale thread
  pool.
