It would be great if you could provide a stack trace showing the NPE. A workaround that you can try is to leave maxActive = -1 but set WHEN_EXHAUSTED_ACTION to WHEN_EXHAUSTED_BLOCK. That may correct the sync and will achieve the same end result as negative maxActive means no limit to the number of available instances.

The workaround is exactly what I ended up doing. Haven't had issues with it so far, but didn't yet test it at the scale where we found the original NPE. Best Regards, Leonid.
