model parameter changes always result in NPE

[jjYBdx4IL]

using the latest release, whenever I change a model parameter, like enabling leaves, an NPE is thrown. Win 10 amd64, oracle jdk 10.0.1.

What version of Java are you using?

[jjYBdx4IL]

oracle jdk 10.0.1, amd64, windows 10 latest

[pspeed42]

I think jme has problems with that Java. You might try an older one.
