YourSQL and "no document could be created"

After using the smart little mysql browser YourSQL for one year on my mac, suddenly i could'nt start it any more. It gave me a "no document could be created" error.

Digging a bit gave me hints like the one descriped here (get the right compiled version for intel macs). But since it worked for me already, this couldn't and wasn't be the solution...

The problem was...
Java 6.
I recently made it my default java version.
Switching back to java 5 solved the problem and YourSQL worked fine again!
