Bridj (0.7-SNAPSHOT) Native method overriden in CPPObject broken #534
Description
Sometimes, Java callback from CPP invocation (override a native method with a non-native method in a class extending CPPObject ) throws NullPointerException because BridJ.getJavaObjectForNativePointer return null in native code (CPPToJavaCallHandler_Sub)
getJavaObjectForNativePointer try to find a NativeObject instance in a WeakHashMap<Long,NativeObject> (knownNativeObjects field in BridJ). It's odd to use Long as weak key. They are garbaged very quickly so a null pointer is thrown because NativeObject instance couldn't be found.

Hi @obethery ,
Thanks a lot for taking the time to diagnose the problem and to find a fix!
In retrospect it was a silly design mistake to use a weak hashmap for this, so I've gone for another simpler route... It's in the fresh 0.7.0 release, please let me know if you face any issue with it!
Cheers
