FULL PRODUCT VERSION :
java version "1.4.2_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_02-b03)
Java HotSpot(TM) Client VM (build 1.4.2_02-b03, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Windows NT 5.01
A DESCRIPTION OF THE PROBLEM :
JVM never completes startup when JVMPI is enabled and it is being debugged.
If I was a betting man, I'd say there was some kind of deadlock occurring, because it just hangs, shortly after JVM_OnLoad.
This is a regression, 1.4.2_01 and early works fine.
FYI, problem also occurs with 1.5.0-b26
You wouldn't think it would be much of a problem, but I need to collect coverage data while debugging my program & that requires JVMPI.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
This occurs ONLY on 1.4.2_02, 1.4.2_01 and 1.4.2_00 work fine.
Initializing jdb ...
> run -Xrunhprof -jar Notepad.jar
run -Xrunhprof -jar Notepad.jar
[ VM hangs at this point ]
EXPECTED VERSUS ACTUAL BEHAVIOR :
When it works (for 1.4.2_01, for example), the notepad window opens. :)
JVM hangs at 0% CPU until control-c is pressed.
This bug can be reproduced always.
