    • Regression Test Failure

    Description

      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.
