  ****************************************************************
  01.In Rational Developer for System z - RDz - v9.1.1.2, the
     daemon process may raise an abend 0C4 in function tfree()
     called from
     Java_com_ibm_etools_zos_server_CoreJNI_startProcess()
  

Problem conclusion

• 01.Java_com_ibm_etools_zos_server_CoreJNI_startProcess() has a
     pointer whose value is not initialized in nomal cases. Only
     if a heap area is allocated only in some error conditions ,
     the pointer is initialized to point the allocated area. Even
     if it is not initialized,
     Java_com_ibm_etools_zos_server_CoreJNI_startProcess() tries
     to free the pointed heap area and that could cause the
     abends in tfree(). RDz server code is updated to call
     tfree() only if the pointer points the allocated heap area.
