Subject [jira] Updated: (HARMONY-3895) [drlvm][kernel] Compatibility: Field.getXXX(null) exception throwing order differs on Harmony and RI
Date Fri, 18 May 2007 06:25:16 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-3895?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alexey Varlamov updated HARMONY-3895:
-------------------------------------

             Component/s:     (was: Classlib)
                          DRLVM
    Estimated Complexity: Novice
                 Summary: [drlvm][kernel] Compatibility: Field.getXXX(null) exception throwing
order differs on Harmony and RI  (was: [classlib][luni] Compatibility: Field.getXXX(null)
exception throwing order differs on Harmony and RI)

Changed component as reflection classes are kernel and provided by VM.
