Mike Matrigali updated DERBY-5406:
----------------------------------

    Assignee: Mike Matrigali  (was: Knut Anders Hatlen)

I am looking at backporting this fix to 10.8, so setting ownership to myself.

> The test cases CompressTableTest.testConcurrentInvalidation() and TruncateTableTest.testConcurrentInvalidation()
fail intermittently with errors such as:
> ERROR XSAI2: The conglomerate (2,720) requested does not exist.
> The problem has been analyzed in the comments on DERBY-4275, and a patch attached to
that issue (invalidation-during-compilation.diff) fixes the underlying race condition. However,
that patch only works correctly together with the fix for DERBY-5161, which was backed out
because it caused the regression DERBY-5280.
> We will therefore need to find a way to fix DERBY-5161 without reintroducing DERBY-5280
in order to resolve this issue.
