As you have probably seen IPC connection seems to be not yet

Is this reproducable? I'm afraid, that if there's a bug in the code in
this area, you will have same problems with 1.5 - we did not change

You just change the URL to

jdbc:firebirdsql:native:host/port:/path/to/your/db.gdb

Also jaybird.dll/libjaybird.so must be in the path.
