Test : nsk/regression/b4340444
TestBase : testbase_nsk

The nsk/regression/b4340444 test fails to get matching between NotifyFramePop()
function calls and JVMDI_EVENT_FRAME_POP events under the HotSpot VM
(build 1.4.0-rc-b85).

This test calls the NotifyFramePop() function for every methods of the b4340444a
class and then expects that the JVMDI_EVENT_FRAME_POP event should be generated.

But the test shows that some JVMDI_EVENT_FRAME_POP events are lost and this
failure is shown starting with HotSpotVM (build 1.4.0-beta3-b81).

This failure happens on all platforms.


To reproduce the bug run in GammaBase/Bugs/<this bug number> directory:

Please note that the attached in Gammabase nsk/regression/b4340444 test
is not the same as in the promoted testbase_nsk.v14r08.

This test was fixed according to #4445833 bugreport and it'll be promoted
with the testbase_nsk.v14r10 release.
