Hello,

I hope this is the correct place to report an issue. I am trying to convert our product from using CORBA in se to Glassfish/ee. I don’t know the details of this code and my proposed solution might not be correct but I hope the problem is clear.

 

Thank You

Line 999

                } finally {

                    if (readLocked) { readUnlock() ; } // Issue 14917: was unlock()

                }

Should read

                } finally {

                    if (readLocked) { readUnlock() ; readLocked = false ; } // Issue 14917: was unlock()

                }

 

By not setting readLocked to false the cleanUpLocks call will throw the exception

cleanUpLocks( child, readLocked, writeLocked, childReadLocked ) ;

 

Example exception:

java.lang.IllegalMonitorStateException: attempt to unlock read lock, not locked by current thread
