Subject Re: OOM with JDBCConfigurationImpl holding 1+ GB of heap
Date Fri, 10 May 2013 17:05:22 GMT
I'm in the process of verifying if Kevin's suggestion fixes the problem.

While making the necessary changes, I've notice we were already enhancing
the classes at build time.

If the classes were enhanced at build time, still would be we see the leak
if the runtime enhancement flag is enabled?

Thanks
