Subject: [PATCH] fixes hashCode overflow. (disclamer: i wont talk about
 collision probabiliity or whatever. In my point of view, it seems very low,
 as the id() is based on the address of the object, it except if you uses tons
 of memory, you wont get it. And whatever the changes are, this will never
 keep up safe from colliding with others java object.). Closes #146
