Subject [jira] Commented: (HARMONY-2889) [jdktools][jdwp] group identical Breakpoint, Step, MethodEntry, MethodExit events
Date Sat, 07 Jul 2007 10:44:04 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-2889?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12510874
] 

Ivan Popov commented on HARMONY-2889:
-------------------------------------

The following affected JDWP stress tests passed with patched JDWP agent:

  org.apache.harmony.test.stress.jpda.jdwp.scenario.EVENT011.EventTest011
  org.apache.harmony.test.stress.jpda.jdwp.scenario.EVENT012.EventTest012
  org.apache.harmony.test.stress.jpda.jdwp.scenario.EVENT013.EventTest013

but the following tests still fail due to other issues:

  org.apache.harmony.test.stress.jpda.jdwp.scenario.EVENT014.EventTest014
  org.apache.harmony.test.stress.jpda.jdwp.scenario.EVENT015.EventTest015
  org.apache.harmony.test.stress.jpda.jdwp.scenario.EVENT016.EventTest016 

I'll submit new issues separately.

> According to JDWP spec Breakpoint, Step, MethodEntry, MethodExit events for the same
location can be grouped into one event set. Without this feature user have to resume thread
twice when, for example, stepping over a line with breakpoint.
> Current implementation of JDWP agent groups only identical events, it does not group
different events into one event set. Implementing grouping for different JDWP events based
on JVMTI callbacks requires rather sophisticated algorithm.
