APAR status

• Closed as program error.

Error description

• An 0C4 abend can occur after calling through to Java from an
  Input node if the Java environment pointer associated with the
  thread context is invalid. The dump traceback stack may be a
  number of calls into Java by the time the exception occurs,
  but it might contain the following WMB calls:
  
  ImbJniNode::getAttribute
  ImbJniNode::dispatcher
  ImbJniNode::Parameters::run
  ImbThreadPoolThreadFunction::run
  ImbOsThread::innerThreadBootStrapWrapper
  ImbOsThread::threadBootStrap
  threadBootStrapWrapper

  PROBLEM SUMMARY:
  An abend may occur after a call into Java from an Input node
  if a new thread is started that uses an old thread context
  number, which still holds
  a reference to the freed Java environment context.
  
  There are a number of resource name changes between WebSphere
  Message Broker and IBM Integration Bus Version 9.0. For
