The following nsk test fails:
  nsk/jdb/exclude/exclude001

OS: Windows NT 4.0, Windows 2000
JDK builds: jdk1.4.1-beta-b10, jdk1.4.0-b92
VMs : Client, Server
VM mode: mixed, comp, int

The test fails with error message:
## ERROR: Cought unexpected exception while executing the test: nsk.share.Failure:
Attempt to send command :untrace methods 0x14f to terminated jdb.
## ERROR: TEST FAILED

This test failure is caused by abnormal debugged VM's termination.

If the debugged application runs on java_g, then the following assertion is
hitted :

Assertion failed: (char*)p >= sbrk_base, file ../../../src/share/back/dlAlloc.c, line 496
The application has been disconnected

Being run on java, the debugged Server VM when crashing intermittently
outputs this error message:

> An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : EXCEPTION_ACCESS_VIOLATION occurred at PC=0x6D267415
Function=[Unknown.]
Library=h:\ld24\java\hotspot\jdk1.4.1\win\jre\bin\jdwp.dll

NOTE: We are unable to locate the function name symbol for the error
      just occurred. Please refer to release documentation for possible
      reason and solutions.

------------------------------------------------------------------

Test description:
The test checks jdb's 'exclude' command.
The debugged application (exclude001a.java) consecutevely creates three additional threads.
The 'run' method of these threads invokes java.lang.System.currentTimeMillis() and
com.sun.jdi.Bootstrap.virtualMachineManager() methods. For each test case the correspondent
MyThread thread is started and suspended at a breakpoint. Then method tracing is turned on with
'trace methods <thread id>' command with various exclude filtering.

How to reproduce failure:
 1. cd /net/sqesvr.sfbay/export/vsn/GammaBase/Bugs/{this_bug_number}
 2. sh doit.sh <JAVA_HOME> <DEBUGGED_VM_OPTIONS>
  where <DEBUGGED_VM_OPTIONS> should contain -Xcomp option.

If you wish to use java_g as debugged VM then change the option to
-debugee.vmkind=java_g at command line 47 of doit.sh.

The test will appear in the next testbase_nsk r14 release.
