Problem Description : nsk/jdi/Scenarios/invokeMethod/redefineclasses001 fails because static field value was not changed
                         as it was supposed to be done after class redefenition.

Java Release : 6u10-b09 (didn't ry with other builds), jdk7-b24 (didn't ry with other builds)
VM flavors : client | server
VM Modes : -Xmixed | -Xcomp | -Xbatch
Java flags :
Platform(s) : linux-i586 (didn't try on other platforms)
Hostnames with OS info : vm-v20z-21.sfbay (Red Hat Enterprise Linux Server release 5)

Suite Name : nsk.jdi
Test cases : nsk/jdi/Scenarios/invokeMethod/redefineclasses001


This test is based on a scenario which consists of the following steps:
   1. Invoking debuggee's static method by ClassType.invokeMethod().
   2. Redefinition of this method (using new version of the class)
   3. Invoking the one again.
   4. Redefinition of this method (using old/original version of the class)
The test checks a value of static field to be equal to new value.
When the field has unexpected value, the test fails.

This scenarios is actually repeated 2 times (=> 2 test cases in the test):
1. "0-case"
   during first time (debuggee is stopped at line 32)
   there is no active stack frame of the method runIt of class redefineclasses001b
   (the class which is redefined)

2. "1-case"
   during second time (debuggee is stopped at line 40)
   there is active stack frame of the method runIt of class redefineclasses001b.

The test fails sometimes (for me it was reproduced every ~10 times) during the second case.
I was able to reproduce the failure with recent
6u10-b09 (HS_11) and jdk7-b24, with -client/-server and
-Xmixed, -Xcomp, -Xbatch modes.

Here is the error log:
