HotSpot Client VM loses the JVMDI_EVENT_BREAKPOINT events on win32

Name: dkC59003 Date: 01/10/2000


The regression test (testbase_nsk) nsk/regression/b4289162 fails
under the HotSpot Client VM (build 1.3-R) on win32.

The test sets breakpoint in the emptyMethod() method which is called in loop
(5 times). When the breakpoint is caught for the first time the test
enables the JVMDI_EVENT_SINGLE_STEP event and when
this event is caught the test disables the JVMDI_EVENT_SINGLE_STEP
event . After this the JVMDI_EVENT_BREAKPOINT events are not sent any more.

The same happens for not-empty method.

To reproduce the bug run doit.bat on win32 in
/net/sqesvr/vsn/GammaBase/Bugs/<this bug number>.

The first parameter for doit.bat should be JDK root directory
(e.g. L:/java/jdk1.3/win32) and the other parameter(s) -
VM option(s) (optional).

The Classic VM runs the test perfectly.
