Hi,
Still same issue with Snow leopard 10.6.4, java 1.6.0_24 and max 5.1.7.
Here's what max says:

And recompiling the *.java doesn' change anything, for instance:

I don't knwow what else to do.
Reinstall max doesn't change anything.
And right away, it does work with max 4.6 on the same machine………

cant-load-any-mxj-with-max-5-1-7-and-leopard-snow

We were experiencing this problem as well on the Mac last night. We used Application->Utilities->Console, clear it and re-run max. We found there were some strange pro-tool drivers that were messing up and crashing our system. Also, it was having trouble reading our defines in the Max.config file (perhaps some pesky unicode characters snuck into the file). We saw that java complained it couldn't understand a define, and failed to load the MXJClassLoader.

ich schließe mich dieser Problematik an!

in my system xp home sp3 under MaxMsp Jitter 4.6.3 mxj mxj~ works without any problems

but if I tried to using now Max-Gen ver.6.0.8 the same problem

"unable to create JVM" etc.and no MXJ-paths are list on startup in the Max-window

javac.exe doesn't look like a max.system.jar.dir to me...


but, ist the syntax wrong or what? this is the max.java.config.txt which works well with MaxMsp 4.6.3 in xp home sp3,

for information: I've tested Java in MaxMsp 4.6.3 under my 10.5.8-osx-system,

sure: at first I've recompile all written java-mxj's etc and it seems ok

with software-update I've update the jdk to ver.1.6.0 and the terminal shows the java-version correctly

but if I try to load e.g. a patcher which includes several mxj I've got in the Max-window this:
