Mike Matrigali commented on DERBY-5624:
---------------------------------------
i'd appreciate it if someone good with junit could review my new test. Most
critical would be if it has the appropriate decorators. I could move the new
test to the end if we think it is affecting the other tests, or alter the test
to drop the table sooner (I was assuming the table would get
dropped automatically). The new test really should not be that much of a drain
on disk space, compared to the rest of the tests as it mostly
adds 1000 small files.
I can also back out test on windows also if we think it is causing problems
there.

> Key: DERBY-5624
> URL: https://issues.apache.org/jira/browse/DERBY-5624
> Project: Derby
> Issue Type: Bug
> Components: Store
> Affects Versions: 10.8.2.2
> Reporter: Mike Matrigali
> Assignee: Mike Matrigali
> Labels: derby_triage10_9
> Fix For: 10.9.0.0
>
> Attachments: DERBY-5624.patch, error-stacktrace_mod.out,
> largedatasuite_mod.out
>
>
> The system currently recursively calls xact.notifyObservers() from
> DropOnCommit.update(). It does this because in some cases
> new observers can be added while processing the list of notifyObservers and
> those were being missed before the change, causing
> Assertions in the tests and possibly files not properly dropped on commit.
> Multiple users on the Derby user list have had failures running
> SYSCS_UTIL.SYSCS_COMPRESS_TABLE(), running out of stack track
> with a heavily recursive stack trace of the form (see more detail from these
> reports in subsequent comments):
