Knut Anders Hatlen updated DERBY-912:
-------------------------------------
Attachment: derby-912.diff
Attaching a patch which implements reuse of sort identifiers, as suggested by
Mike.
I have successfully run the repro for DERBY-756 without getting
OutOfMemoryError. I have also run the full set of regression tests (derbyall +
JUnit) with no failures.
The patch is ready for review. Thanks!

> After fixing the original memory leak, I still run into problems on repeated
> execution of a sql statement. Take the sample program in the bug and run it
> with a small heap size (4m). After around 80-90K executions an outofmemory
> error is thrown. I took snapshots of the heap while the program was running
> but couldn't find anything obviously wrong.
