Ivan Popov updated HARMONY-2889:
--------------------------------

    Attachment: H2889_jdwp_tests.patch

Second patch 'H2889_jdwp_tests.patch' adds new test cases to JDWP unit tests:

  org.apache.harmony.jpda.tests.jdwp.Events.CombinedEventsTest
  org.apache.harmony.jpda.tests.jdwp.Events.CombinedEvents002Test
  org.apache.harmony.jpda.tests.jdwp.Events.CombinedEvents003Test

which tests generation of combined JDWP events.

> 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.
