The specification for the method ReferenceType.isStatic():

    public boolean isStatic()
        Determines if this type was declared static.
        Only nested types, can be declared static,
        so false is returned for any
        package-level type, array type, or primitive class.
    Returns: true if this type is static; false otherwise.

states that if the method is being invoked on a mirror of an array
the returned value is false.

However, a test shows that
if an element type is InterfaceType or static ClassType
the returned value is true.


This unspecified result is observed
when HS 1.4.0-beta-b83 is runnning a test program
on the following H/S configurations:

 - SUNW Ultra1: sparc 200MHz, RAM 128Mb;
   OS: Solaris-8;
   JVM: Client & Server
 - Intel: 2-processor i686 600MHz processor, RAM 512Mb;
   OS: Solaris-8;
   JVM: Client & Server
 - Intel: 2-processor i686 600MHz processor, RAM 512Mb;
   OS: Linux/RedHat6.2;
   JVM: Client & Server
 - Intel: Pentium-II 350MHz, RAM 128Mb;
   OS: WinNT/4-Workstation;
   JVM: Client & Server


Corresponding code fragments in a debugger and a debuggee
and corresponding log for the tested case are below.


Steps to reproduce the bug:
1. cd /net/sqesvr.sfbay/export/vsn/GammaBase/Bugs/{this bug ID}
2. sh doit.sh {JAVA_HOME}


    This bug affects the following testbase_nsk test:
    
    nsk/jdi/ReferenceType/isStatic/isstatic002


The tests will be in the next release of testbase_nsk;
the current release of testbase_nsk (1.4) is accessible through:

    /net/sqesvr.sfbay/export/vsn/VM/testbase/testbase_nsk.v14
