    Issue & fix info: Patch Available
> Intermittent failures in CompressTableTest and TruncateTableTest
> ----------------------------------------------------------------
>                 Key: DERBY-5406
>                 URL: https://issues.apache.org/jira/browse/DERBY-5406
>             Project: Derby
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions:,
>            Reporter: Knut Anders Hatlen
>            Assignee: Knut Anders Hatlen
>         Attachments: d5406-1a-detect-invalidation-during-compilation.diff, d5406-1b.diff,
d5406-2a-invalidate-self.diff, d5406-3a.diff
> 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.
