HotSpot 1.4.0beta-b51 fails to pass the test

nsk/jvmdi/PopFrame/popframe004

from testbase_nsk on all platforms. The VM crashes with the error ID
4F530E43505002C3 (os.cpp, 707).

The test checks that a method's frame can be popped by the JVMDI function
PopFrame() from a thread, which is different than a tested thread.
The tested thread executes the inner class popFrameCls (see the source file
popframe004.java). In that thread the Java method run() calls the native method
nativeMeth(), the native method nativeMeth() calls another one native method
nativeMeth2(), which finally calls the Java method activeMethod().
This activeMethod()'s frame the test from another thread tries to pop.
The frame is successfully popped, but when the test resumes the tested thread,
the VM crashes with the error mentioned above.

To reproduce the bug run
doit.ksh <jdk root directory>
in
/net/sqesvr/export/vsn/GammaBase/Bugs/<this bug number>
