The issue seems to be caused by commit 2910e2fddcd4f4c4669c14d0bbd81e7b213462bb, which added the jnius_config module to manage java class paths. Previously, os.path.realpath('.') had been added to the class path in jnius_jvm_desktop.pxi, which ensured that org/jnius/NativeInvocationHandler was available, but now there are no entries added to the class path by default, so the class is no longer available. This could be resolved by inserting the path in jnius_config.get_classpath after the path is constructed from the environment or the configured list.

It's a bit more involved than my previous comment suggests. The NativeInvocationHandler class file is not being included in the installation package and in addition, no attempt is being made to add its location to the java class path. I've fixed this in a fork of the physion fork, see commit 26f1367ab143cd72203f0db77556279eac8c304f for details. This fix should be easy enough to port to the kivy branch if anyone is interested in doing that.

I am also having this issue... +1 for merging this patch.

[rbrewer123]

I'm having this issue too with a fresh build. +1 for merging.

[AndreMiras]

Any reason why this is still not merged?

[AndreMiras]

FWIW, maybe my issue was a little bit different. But I eventually got it working (without the patch) by calling autoclass('org.jnius.NativeInvocationHandler') once in the main thread.
