> 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):
