Java and Lion

After upgrading my MacBook Pro to Lion, I got an error when running SoapUI (v4.0.0). The app launched, but as soon as I clicked anywhere in its windows, I saw the following stacktrace

Turns out this is caused by running the 64-bit version of Java (this is the default setting). By changing the order of the 32 and 64 bit versions in the Java Preferences application (/Applications/Utilities), Java now runs in 32-bit by default and SoapUI works again.

I probably could also changed the soapui.sh file and pass in the -d32 parameter manually.
