Looks good to me. (Not a reviewer, though). Thanks for fixing it. My bad...

7180769: assert(tboth->klassisexact()**) failed: klass should be exact Regression after 7170463 changes. Result of join() with interface class produces non-exact type: tcon: precise klass java/lang/String: 0x0000000111a57dd8:Constant:**exact * tval: Interface:klass org/apache/derby/iapi/store/**raw/xact/TransactionId: 0x00000001174cc278 * objtype: org/apache/derby/iapi/store/**raw/xact/TransactionId:NotNull * tboth: org/apache/derby/iapi/store/**raw/xact/TransactionId:NotNull * Use class exactness as part of the condition for class compare optimization instead of assert. Tested with failed test. Thanks, Vladimir -------------- next part -------------- An HTML attachment was scrubbed...
