  PROBLEM DESCRIPTION:
  The DataFlowEngine may crash due to parser going out of scope in
  the following conditions
  i. JavaCompute node in flow modifies InputLocalEnvironment
  object and is copied into another message tree
  ii. Flow rollbacks due to failure after the JavaCompute node
  that modifies InputLocalEnvironment
  iii. The copied LocalEnvironment tree is referenced in the
  failure path of the flow

  crash due to out of scope object referencing.
