Regression test java/util/Date/bug4323273.sh is failing again with Merlin build 64 on sol2.8x86, host schist.  This failure is timing out rather than the exit code 1 from the previous occurance of this failure.  It times out on a fast machine when run as a local stand alone test.  If you have any questions, please eMail me at ###@###.###
 For test hardware config's, see http://sqesvr.eng/st3/jdk1.4/docs/Merlin-hw.html

The regression test java/util/Date/bug4323273.sh is failing on Linux 7.1 for the reasons that Mark has outlined in bug 4480926. Because of this failure of this test, more than 600 other regression tests are failing.  Mostly because of the unstable condition this test leaves the machine in.  This test also fails on win98 but not Win NT or win2000.  On Solaris this test passes with no problem.

EVALUATION It sometimes (not always) takes several minutes to schedule the main thread of mtthread.java which controls the execution. 20-40% of executions failed with timeout on schist due to this. Giving a higher priority to the main thread will fix this problem. (Note that one execution takes 4 to 8 minutes on the same system (schist) even with the fix. The JRE binaries should be on a local disk.) masayoshi.okutsu@Eng 2001-05-25 The fix was tested on Solaris 8 P2/825MHz (schist), Solaris 8 Ultra 60/450MHz, Solaris 8 Ultra-1/167MHz, Windows 2000 P3/933MHz, Arabic Windows 2000 P2/400MHz, Japanese Red Hat 6.2 P2/400MHz. masayoshi.okutsu@Eng 2001-05-25 Calling gc() seems to cause deadlock since b63b. Need to remove the gc() call. masayoshi.okutsu@Eng 2001-06-11 Since this bug report status has been changed for the same problem as 4480926. I'm closing this one as a dup. This shouldn't have done, though. This bug report is losing the correct history (unless looking at the change log). masayoshi.okutsu@Eng 2001-07-24
