is there a best practices for multithreading in jmonkey? I created a hashtable in the simpleInitApp, which I can write to in another thread and then always work through in the simpleupdate(). But its not doing anything. The reason I created this hashtable was because removing or adding a node to the rootnode from this other thread sometimes created a thread error. But now its not attaching or removing anything from the rootnode. Any ideas?
