Local fix

Problem summary

  • When J9VM is requesting a new encoding module through iconv()
    function family, a switch must be made from J9VM thread to the
    IPT (Initial Program Thread)  to load the requested module into
    LE. Under CICS, IPT returns after completing JVM creation and
    discards its LE context . A JVM thread  wakes up for logging
    purposes. It invokes an iconv call (ie character conversion of
    some kind) which triggers a switch to IPT as the requested
    encoding module is not represent in LE.  In this situation,
    since IPT no longer holds a valid LE context, a crash occurs.
    

Problem conclusion

  • This defect will be fixed in:
    5.0.0 SR12
    6.0.0 SR9
    .
    The JVM has been updated to "pre-load" the UTF-8 character
    encoding module at JVM initialization time when a IPT is
    present.
