Test : nsk/jdi/Scenarios/invokeMethod/popframes001
Test Base : testbase_nsk
VM : ServerVM, ClientVM
Mode : comp, int, mixed
Platform (s) : solx86, linux, solsparc, win
OS : 5.8, RH7.2, NT/2000
JDK : 1.4.2-b03, hopper-rc, merlin-rc
------------------------------------------------------------------------------
Debuggee's part of the test contains a tested class (class B) and
debugger exercises method runIt() of this class by the following steps:
1. On ClassPrepareEvent of class B, MethodExitRequest is created and
   debugger waits MethodExitEvent for <clinit> to be shure the static
   members of class B have been initialized
2. After getting MethodExitEvent for <clinit>,
     - debugger creates MethodEntryRequest
     - invokes the tested method (method "runIt") by calling
       com.sun.jdi.ClassType.invokeMethod().
   This invoking occurs in special thread of debugger's part so that
   debugger can process the events of the target VM.
3. When getting MethodEntryEvent from the invoked method (method "runIt"),
   debugger tries to pop current frame (with 0 index).

Result of the last step is that debugger hangs.

The test will be available in testbase_nsk.v142r18
