------------------------------------------------------------------------------
Test : nsk/jdi/BScenarios/multithrd/tc04x001
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-b02
------------------------------------------------------------------------------
The test performs next steps:
- debugger creates MethodEntryRequest on specified class
- debugee starts three threads that call a method of the specified class
- after getting MethodEntryEvent, debugger checks location of this event.
InternalError exception may be thrown, while debugger is trying to get
a location of the arrived MethodEntryEvent.

The test is reproduced on Windows more frequently. But the failures may
be observed on other platforms too.

The test will be available in testbase_nsk.v142r17

doit.sh script executes the test $ITR_NUM times or until it fails.

Steps to reproduce
==================
1. cd /net/sqesvr.sfbay/export/vsn/GammaBase/Bugs/<BugID>
2. sh doit.sh $JAVA_HOME [$ITR_NUM]
        where $ITR_NUM - number of iterations to execute the test,
                         default value is 10

An example of the test's output:

TEST BEGINS
===========
 event ===>>> VMStartEvent in thread main

--------------------------------------------------------
 event ===>>> MethodEntryEvent arrived

Also the above test sometimes fails due to debugger do not
get some expected MethodEntryEvent's.

In this case test's output looks like:

TEST BEGINS
===========
 event ===>>> VMStartEvent in thread main
MethodEntryRequest created, expecting events from method "foo"
--------------------------------------------------------
 event ===>>> MethodEntryEvent arrived
event info:
        thread - main
        source - tc04x001a.java
        method - main
        line - 24
the event skipped, method - main

 event ===>>> MethodEntryEvent arrived
event info:
        thread - main
        source - tc04x001a.java
        method - <init>
        line - 46
the event skipped, method - <init>

 event ===>>> VMDisconnectEvent
# ERROR: debugger FAILURE> expecting 3 MethodBreakpoint events, but 0 events arrived.
=============
TEST FINISHES

Test finished. exitStatus = 2


#>
#> SUMMARY: Following errors occured
#> during test execution:
#>
# ERROR: debugger FAILURE> expecting 3 MethodBreakpoint events, but 0 events arrived.
exit code = 97
