Trouble Running 1.1b2

I'm using java 1.5.0_13 on my Mac and I get the following when I try to run InitTool 1.1b2.

Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file
at java.lang.ClassLoader.defineClass1(Native Method)

I haven't downloaded the code and tried to find the issue yet, thought I'd ask in case this was a known issue, or I missed something obvious first.

Thanks,
Steve

I wonder if 1.1b2 is built under Java 6?

Version 1.1 of Init Tool uses Java 6. That provides the scripting framework.

OK, not that you will want to change anything for Mac support but Java 6 is not currently available on Mac. There is a beta available for Leopard (OS X 10.5), but you're few mac users probably don't have Leopard or the beta yet.

InitiativeTool 1.1b2 is only the second build in the development version. I am guessing that Jay wouldn't be all that worried about that sort of thing until it got closer to release. 1.0b23 is the current release version.

Actually I am hoping that Apple will hurry up and release Java 6 on the Mac before long. The 1.1 version will require Java 6 because Java 6 has all of the scripting support in it including the JavaScript parser. Until then you will have to use the 1.0 version which runs on Java 5. Apple is moving way too slow on this.

I'm actually getting the same problem, but I've installed the java 6 package from the apple dev tools website.

EDIT: changing the j2se version to 1.6+ in the jnlp file does the trick.

Ooop, so now it's launching but I'm getting a reflection error.

That is most likely a problem I had with the Sun JavaScript parser. Apple must be using a different one. I'll get it fixed in the next build.
