HS running tests against ArrayType.newInstance() method,
crashs when newInstance() method is applied to
ArrayType objects in a debugeer
mirroring arrays in a debuggee
whose components are either classes or interfaces,
that is, non-primitive values.

The crashes are observed
for JDI versions 1.3.1-rc1-b17 and 1.4.0-beta-b52
when HS 1.3.1-rc1-b17 or 1.4.0-beta-b52 is runnning a test program
on the following H/S configurations:

 - SUNW Ultra1: sparc 200MHz, RAM 128Mb;
   OS: Solaris-8;
   JVM: Client & Server
 - Intel: two Pentium-III 600MHz processors, RAM 512Mb;
   OS: Solaris-8;
   JVM: Client & Server
 - Intel: two Pentium-III 600MHz processors, RAM 512Mb;
   OS: Linux/RedHat6.2;
   JVM: Client & Server
 - Intel: Pentium-II 350MHz, RAM 128Mb;
   OS: WinNT/4-Workstation;
   JVM: Client & Server

Note: When running on Solaris-8, both hardware platforms,
      the tests resulted in Core dump.

Test logs and core dump log files are below.



Steps to reproduce the bug:
1. cd /net/sqesvr.eng/export/vsn/GammaBase/Bugs/{this bug ID}
2. ksh doit3.sh {JAVA_HOME} or
       doit4.sh {JAVA_HOME }
       (see 'Note' related to '// log by doit4.sh' below)



The tests will be in the next release of testbase_nsk
which is accessable through:

    /net/sqesvr.eng/export/vsn/VM/testbase/testbase_nsk


    This bug affects the following testbase_nsk tests:
    
    nsk/jdi/ArrayType/newInstance/newinstance003
    nsk/jdi/ArrayType/newInstance/newinstance004
