SFSB expiration failures cause memory leak

      Configure attached Byteman script that triggers the bug.

      Attached reproducer contains a simple EJB and a jsp (http://localhost:8080/test to run) that calls the EJB to trigger the bug, waits to give expiration a chance to run, then tries to call the EJB again. The JSP logs "PASS" or "FAIL" to stdout.

      Note: SFSB in reproducer has a 1 minute timeout in order to trigger the bug somewhat quickly, and the byteman script waits accordingly. The wait would need to be increased for a longer SFSB timeout.

    Description

      There is a timing bug where SFSB expiration can run while the SFSB is still locked, causing the expiration to fail and never retry, leaving the SFSB active indefinitely.

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-16601 [GSS](7.2.z) SFSB expiration can fail

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
