[SOLVED]Mac OS X Intel 64-bit + Java 6 + jsr-231-webstart-current = exception?

OpenGL Development JOGL Development
#1

Has anyone else experienced the following exception when running JOGL under the conditions listed in the posting subject line? I had no problems developing with JOGL or running JOGL webstarts (using jsr-231-webstart-current) when using Java 5, but when I switch to Java 6 (for webstarts) I get the following exception:

Any hints appreciated.

Please port CPU detection (32/64 bit) to your platform (mac os x/x86_64)

i guess JOGL can’t parse the CPU string when run on the apple 64bit vm.

it should be fixed in 1.1.1 - can’t explain why this is happening (maybe clearing the webstart cache solves it already).

Thanks for the quick reply. The link to the source code of CPU.java was enlightening.

In the meantime I found the following thread in this forum regarding this problem:

Now I’m trying to follow the advice in the above thread, where the blame is laid on old copies of gluegen-rt.jar lying around in system folders.

I found the offending copy of glugen-rt.tar, removed it, and everything works fine.
