Kathey Marsden updated DERBY-4489:
----------------------------------
Issue & fix info: [Newcomer, Repro attached] (was: [Repro attached])
Urgency: Normal
Labels: derby_triage10_8 (was: )
Triage for 10.8. Marking normal urgency as it seems to impact a test suite
running against Derby. Marked newcomer as it probably would not be too hard to
fix this one case. In general, however it should be noted that the client is
not well behaved and can get protocol errors and other symptoms when the server
exits while it is still connected. A general fix would be a bigger project.
