 Replying to [comment:8 jnd]:
 > Hi David, there seem to be two or three issues beneath the surface.
 Either way, I think it's a bug with Apple's Java Application Launcher.
 FYI, my JVM preferences were:

 The combination of this list and the default setting `1.5+` for
 `JVMVersion` in Info.plist *should* select Java 6. Looks like a bug in the
 application launcher, yes.

 > Secondly, I noticed that I was missing the 32-bit version of Java 6
 (i386). I manually inserted it into my Host-specific preferences. That is,
 I edited

 Does it launch with `JVMVersion` set to `1.5+`?. We do have a runtime
 architecture preference in the `Info.plist` for `i386 ` before `x86_64`
 which could have a bad influence here.

 Nevertheless, it should work with either ''Java 5 x86_64'' or ''Java 5
 i386'', too. The error message indicates that we have a class that is
 compiled for Java 6 only but I don't think that is the case as I run it
 successfully on a Java 5 VM/PPC and there would be many more bug reports.
