Error description

  • Under stress it could be that the performance of Business
Process Choreographer will not scale as expected as code in
class com.ibm.bpe.database.Tom.assertBpelProcessTemplateInCache
is synchonizing it's execution so that Java locks are blocking
the execution of business processes or human tasks.
With this interim fix the synchronization within this class
will be reduced to it's minimum to prevent extra Java locks.
