Subject Re: [Firebird-Java] FBManagedConnection
Author David Jencks
I made several changes that I think will fix this problem. I would
appreciate it if you can try the driver from cvs and see if this problem is
fixed. If this and the serialization problems are fixed I will release a
new binary RC2 in a few days.

Thanks
