Subject [jira] Resolved: (HARMONY-2889) [jdktools][jdwp] group identical Breakpoint, Step, MethodEntry, MethodExit events
Date Tue, 24 Jul 2007 16:24:33 GMT

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

Gregory Shimansky resolved HARMONY-2889.
----------------------------------------

    Resolution: Fixed

Patches are applied at 559093. The new test CombinedEventsTest stably fails on win32 (for
some reason linux ia32 works) because VM fails on assertion in JVMTI single step code. The
bug is probably not related to JDWP because single step shouldn't behave like this, but this
test may be excluded if we don't fix the bug quickly. Please check that the patches are applied
as expected.

> 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.
