Subject [jira] Commented: (HARMONY-1433) [DRLVM] Not all scratch registers are restored after watchpoint notification in JET.
Date Fri, 15 Sep 2006 20:19:25 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-1433?page=comments#action_12435107 ] 
weldon washburn commented on HARMONY-1433:

I am OK with committing this patch.  It looks like all the mods are to Jitrino.JET.  Perhaps
the following has already been done.  Is there a way of building an automated test script
for the JVMTI interface?  Maybe some java code that sets a breakpoint, single steps, sets
watchpoints, etc.

>         Attachments: HARMONY-1433.patch
>         Watchpoint implementation was fixed to restore all scratch registers correctly.
>         Corresponding methods were also refactored.
>     Short scenario to reproduce the bug:
>             JVMTI agent should request watchpoint capabilities (can_generate_field_access_events,

>             can_generate_field_modification_events) and DRLVM will throw NPE due to corrupted

>             stack after notification code.
>     The jira depends on HARMONY-1363
