APAR status
Closed as program error.
Error description
Historically the COBOL runtime has created a JVM as required, but did not explicitly terminate it. In some cases this leads to thread termination failures in the C/C++ runtime.
Local fix
Include application code to terminate the JVM; sample code available on request.
Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL V5 and later * * releases running COBOL programs that make * * use of Object-Oriented features to interact * * with Java. * **************************************************************** * PROBLEM DESCRIPTION: C/C++ runtime library abended * * intermittently during Language * * Environment Enclave termination when * * freeing storage belonging to a thread * * that had already been terminated. * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * **************************************************************** When the OO COBOL application terminated, all COBOL storages and resources were freed and cleaned up. But the JVM, being a C++ application, was still active at this point. Later when the JVM was destroyed, the cleanup process attempted to free storage that had been freed. This led to ABEND in the C/C++ runtime during termination processing. COB0501T/K COB0502T/K COB0601T/K COB0602T/K COB0603T/K
Problem conclusion
An environment variable has been added to control the destruction of JVM at COBOL termination. If this environment variable is set to 1, COBDESTROYJVM=1 the JVM will be destroyed when the COBOL main program returns (via STOP RUN or GOBACK statements). This would resolve the issue described in Problem Summary.
