Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server                                      *
  *                  Liberty Core                                *
  ****************************************************************
  * PROBLEM DESCRIPTION: Liberty fails to start, with an         *
  *                      exception in ThreadPoolController.      *
  ****************************************************************
  * RECOMMENDATION:  Try again to start the server. The failure  *
  *                  is a race condition which will happen       *
  *                  rarely,                                     *
  *                  and so the next start will probably not     *
  *                  encounter this problem.                     *
  ****************************************************************
  Liberty may occasionally fail to start, throwing an
  IllegalArgumentException from setMaximumPoolSize()
  If the customer tries again to start Liberty, the problem is
  unlikely to reoccur.
