After running some tests on uima-as on a clean windows machine, I

no uima activity was running) for several hours, overnight, and can
see there is no memory leaks. There is some behavior that I don't
understand, though - I'm wondering if anyone has delved into this
and can explain what these screen shots show (this is the first time
I've attempted to paste screen shots into mail to the dev list - so
apologies if these don't come thru - we'll see).
I see the screen shots don't come thru. I'll see if I can post to
the wiki...
Wiki did not accept screen shot either... Trying another mail client...
Here's the link to the wiki after I uploaded individually the images for
the screenshots. Would be nice if there was an easier way to do this...

First - the vm-args seem to indicate that maybe Derby is being used
- not sure - but I had thought derby was 'disabled' by our default
configuration?
Then, here are some JMX Summary screens, over 3 time spans - a few
minutes, an hour, and overnight. The memory used drops after maybe
about 1/2 an hour, coincident with some classes being unloaded. The
number of live threads goes up and down on a regular basis.
