Long-running testing of 10.2.1.5

I have run a modified* version of the DOTS ATCJ2 Auction simulation test 
case against the 10.2.1.5 Release Candidate for approximately 8 days (so 
far).

The test was run in remote client/server mode using two Solaris 10 (MU2) 
x86 machines with 2x2.4 GHz CPUs and 2 GB RAM. JVM version was Sun's 
1.5.0_07-b03.

No specific issues seen; test results look similar to previous test runs 
(10.2.1.0, 10.2.0.3 and 10.1.3.0) so far (test still running when this 
message was posted).

Memory usage not critical, but it is increasing slightly over time (heap 
size 128 MB). See attached graph showing tenured (old) space utilization 
(OU_jstat-gc-t.png). Previous 10.2 tests were run up to 40 days without 
seeing any errors.
