Firebird and the jbird driver are on the same machine.
If its important i could put my app (its an Appserver) with jaybird or the database to a client machine, but it's not easy because it happens at customer that is 800 miles away.
I'm using jre 1.3.1_04, before this I'v used 1.3.1_03 with the same problem.
I must use Java 1.3.
