Max6 [mxj] hang

Nov 20 2013 | 11:06 am

Hi folks,

I’m os OSX 10.9, with Max 6, working on a large Java-based project (

If I attempt to instantiate an [mxj] with one of my classes, Max hangs forever. If, however, I first instantiate one of the example Java classes (e.g. [mxj echo]), and then instantiate one of mine, everything runs perfectly.

I’ve tried shuffling things in my Java project around, exporting a Jar instead of letting Max use the class files, tinkering with the settings in the file, moving my one non-max.jar dependency (log4j.jar) to different locations. No dice.

Finally, if I instantiate any of my Java classes in Max 5, everything works perfect.

Any ideas?

Hi Josiah,

Currently, there are some issues with mxj and Mac OS 10.9 and we hope to have a fix soon. As a workaround, I believe that if you unjar your files, things should work ok.

Great, thanks!

I ended up removing my one external JAR dependency entirely – which was only to help with debugging when running unit tests in Eclipse -, and everything seems to be OK. My largest patches load in about ~1 second, which is awesome.

A maybe related issue:

The project is structured to work with Max6’s package system. If I put the project into the packages directory, the very first time (and only the very first time) I open any patch making use of my Java classes, Max hangs for 30-45 seconds.
