Symptoms

Java CORBA Client invoking Tuxedo CORBA objects in transaction mode remains blocked : transaction time-out does not occur.
  - Problem suspected to be in ISH not returning that transaction time-out has occurred.
  - A workaround exists if using IBM JVM.

To reproduce the problem:

JAVA CORBA client connecting to a Tuxedo CORBA application.
1. Creating CosTransactions.Control object to start a transaction
2. Time-out set up to 20 seconds
3. Invoking a method on a remote CORBA object published by Tuxedo CORBA
4. CORBA object lasts more than 20 seconds (to simulate it, sleep() function can be invoked)
5. Nothing happens : client remains blocked

Changes

 On JAVA client side :

Extract of a thread dump generated on JAVA client side :

 To be noted : IIOP client transaction Begin is marked (Bgn = 1) but is neither Committed (Cmmt = 0) nor Aborted (Abrt = 0).
