Problem summary

****************************************************************

*                  Server V7.0                                 *
****************************************************************
* PROBLEM DESCRIPTION: OpenJPA datacache plugins that are      *
*                      not reentrant-safe fail to start.       *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
A deadlock situation may occur during OpenJPA initialization
when a datacache implementation which is not reentrant-safe on
initialization is utilized.  The following Exception is an
example of this problem that was introduced in 7.0.0.5:

[9/1/09 15:56:31:890 CDT] 00000022 ThreadMonitor W
WSVR0605W: Thread "WebContainer : 0" (0000002a) has been
active for 765125 milliseconds and may be hung.  There is/are
3 thread(s) in total in the server that may be hung.

Problem conclusion

The feature that introduced this issue in 7.0.0.5 has been
corrected, eliminating the risk of the datacache's initializer
being invoked recursively.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.7.  Please refer to the Recommended Updates
