ArrayIndexOutOfBoundsException is thrown while calling from EASE scripting engine - Load Python scripting engine - Execute some scripts - Exception will be thrown - It is not reproducible always

Might this be a concurrency problem? The logic of org.python.core.PyStringMap.stringmap_keys seems to me to be thread-unsafe. It gets a collection size, to size the destination array, then iterates the collection on the assumption the size has not changed. This is only based on a cursory inspection of the method named. It would be worth questioning other methods of this class too.
