Re: [eclipselink-users] bug: connection leak in Eclipselink

[James Sutherland <jamesssss@xxxxxxxxx>]

I can't see how any JTA managed connection can be leaked.

I have not seen any connection leaking issue with EclipseLink.

Can you recreate the leaking connection usecase in a test?  Try to narrow
down when the connection leak occurs, to determine what is causing it.
