Rick Hillegas updated DERBY-6701:
---------------------------------
Attachment: derby-6701-01-aa-increaseSleepTime.diff
Attaching derby-6701-01-aa-increaseSleepTime.diff. This increases the sleep
time to 2 seconds. The test runs cleanly for me with this setting.
I think it's probably harmless to commit this patch. However, I have no
confidence that it actually fixes the problem. There's no guarantee that an
additional second is what's needed. It is suspicious that this error has
cropped up only recently. What's going on? An extra long garbage collection
burp? And why?
On the other hand, the 1 second sleep was added by derby-1455 8 years ago.
Maybe napping for an additional second every 8 years is the best we can do.
Other thoughts?
