Date Mon, 05 Mar 2007 05:48:51 GMT

]

Alexey Varlamov updated HARMONY-1172:
-------------------------------------

             Component/s:     (was: Classlib)
                          VM
                Priority: Trivial  (was: Major)
    Estimated Complexity: Novice
                Assignee:     (was: Alexey Varlamov)
                 Summary: [ibm vme][kernel] compatibility: ClassLoader.defineClass(...) throws
NPE on Harmony and NoClassDefFoundError on RI.  (was: [classlib][security] compatibility:
SecureClassLoader.defineClass(...) throws NPE on Harmony and NoClassDefFoundError on RI.)

Fixed drlvm at r514553. 
Leaving this issue open to track similar IBM VME issue, the regression test should be integrated
upon closing the issue.

> The method SecureClassLoader.defineClass(...) throws NPE for class name with "/" while
Harmony+j9 throws NPE and Harmony+drlvm throws IndexOutOfBoundsException.
> For name without "/"  RI and Harmony throws NPE, so it may be 'non-bug diff'.
