The regression test (testbase_nsk) nsk/regression/b4289162 causes crash of
the HotSparc 1.3-Q on Solaris.
The test sets BREAKPOINT in emptyMethod and when BREAKPOINT
is caught the test calls
SetEventNotificationMode(JVMDI_ENABLE, JVMDI_EVENT_SINGLE_STEP, ...)
method, which crashes VM.
It had been checked that the same happens with not-empty method.
To reproduce the bug run doit.sh on Solaris and doit.bat on win32 in
GammaBase/Bugs/<this bug number>.
See logs and java source below.
Comments in java source code indicate the line that causes the crash.
If this line is commented out the HotSparc (build 1.3-Q) does not crash,
but the test fails as it is reported in bug #4294585 - its development
status is NYI (for today).
The test crashes classic VM with bus error.
The test causes crash of the HotSpot 1.3fcs-Q on win32 no matter
there is the line causing crash of HotSparc or not.
The BugReport ID: 4297945 had been filed for this case.

The following fragment in the Description is wrong:
"
Comments in java source code indicate the line that causes the crash.
If this line is commented out the HotSparc (build 1.3-Q) does not crash,
but the test fails as it is reported in bug #4294585 - its development
status is NYI (for today).
"
It's correct version is:
"
Comments in java source code indicate the line that the crash depends on.
If this line is commented out the HotSparc (build 1.3-Q) crashes.
Otherwise HotSparc (build 1.3-Q) does not crash,
but the test fails as it is reported in bug #4294585 - its State
is "evaluated" (for today - 12.21.99).
"
And the corresponding fragment in the java source:
"
// th next line causes crash of the HotSparc (build 1.3-Q)
// if this line is commented out the HotSparc (build 1.3-Q) does not crashes
System.out.println("----> RUN: emptyMethod_call_counter = " + emptyMethod_call_counter);
"
should be the following:
"
// the crash of the HotSparc (build 1.3-Q) depends on the next line:
// if this line is commented out the HotSparc (build 1.3-Q) crashes
// otherwise HotSparc (build 1.3-Q) does not crash
// System.out.println("----> RUN: emptyMethod_call_counter = " + emptyMethod_call_counter);
"
