Tests

    nsk/jdi/MethodExitEvent/method/method001
    nsk/jdi/MethodExitEvent/method/method002

failed against Merlin-beta2 builds b69-b70 on all platforms except SolSparc.
No any MethodExitEvents are received after method has been invoked.

On SolSparc platforms tests do pass against builds b69-b70.
Tests also pass on all platforms against build b68.

These tests verify receiving of MetodExitEvent from debuggee after method
is invoked. First test verifies that the event is received
upon method invokation and has correct references to the request,
thread, class and method. Second test verifies that the event is received
for that method, which is an implementation of an abstract one.

All these tests has the same structure.

Each test consists of two parts - debugger and debuggee.
Debugger launches debuggee and sets two breakpoints before and after
invokation of the checked method. It also creates event request and
starts separate thread for handling received events. Created event
request is initially disabled.

When debuggee reaches first breakpoint, debugger enables event request
and disables it after second breakpoint is reached in debuggee.
Thus, no strange events are expected while testing.

Debugger verifies each received event and counts them all.
Test fails if number of received events differs from expected one.

These tests belongs testbase_nsk and were modified due to fixing test bugs:

    4455653 VMDisconnectedException on resume
    4433805 EventSet.resume() for VMStartEvent resumes thread suspended
            by breakpoint request

Updated versions of the tests will appear in the next r06 release
of testbase_nsk located here:

    /net/sqesvr.eng/export/vsn/VM/testbase/testbase_nsk.v14

To reproduce the bug run 'doit.sh' script located here:

    /net/sqesvr.eng/export/vsn/VM/GammaBase/Bugs/<this bug number>

Use:
    sh doit.sh $JAVA_HOME $JAVA_OPTS
Where:
    $JAVA_HOME: points to Merlin-b70
    $JAVA_OPTS: optional VM keys, such as -d64, -server, -Xcomp, etc.
