Java primitive types will cast to their proper box type when passed
to methods and fields taking Number.

- java.lang.Object and java.lang.Number box signed, sized numpy types
(int8, int16, int32, int64, float32, float64) to the Java boxed type
with the same size automatically. Architecture dependent numpy
types map to Long or Double.
types map to Long or Double like other Python types.

- Explicit casting using primitives such as JInt will not produce an
OverflowError. Implicit casting from Python types such as int or float

- Returns for number type primitives will retain their return type
information. These are derived from Python int and float types
thus no change in behavior unless chaining from a Java methods

JBoolean and JChar still produce Python types only.
