Bruce Schuchardt resolved GEODE-3041.
-------------------------------------
Resolution: Fixed
Fix Version/s: 1.2.0
> CI failure: DistributedMemberDUnitTest.testGroupsInAllVMs fails intermittently
> ------------------------------------------------------------------------------
>
> Key: GEODE-3041
> URL: https://issues.apache.org/jira/browse/GEODE-3041
> Project: Geode
> Issue Type: Bug
> Components: membership
> Reporter: Bruce Schuchardt
> Labels: ci, flaky
> Fix For: 1.2.0
>
>
> This test is failing due to a ForcedDisconnection caused by a flaw in
> handling of duplicate member names. The test testTwoMembersSameName creates
> a member in vm2 that has a member name that conflicts with the one in vm0.
> Vm2 causes the membership manager to perform an unclean shutdown, which makes
> it appear to crash. The crash isn't resolved until testGroupsInAllVMs, or
> perhaps even a different test, tries to join using the DUnit locator and it
> causes the new member to fail.
> Name clashes shouldn't cause an unclean shutdown in the membership manager.
> They should cause a normal shutdown.
