-***FIXME***
-***HACK***
- We've got hell of a problem passing "unsigned int64" to java, as there is no equivalent type
- The closer we can use is "long" which is signed, so only 32 (or 63?) bits are valid
- Plus, even if we are within the "32 bits" capacity, java sometime screw itself trying to convert "unsigned 64 -> signed 64"
- This happen especially often when RETURNING a jlong
- So when returning a jlong, we should convert it like this : "unsigned 64"->"signed 64"->jlong
