FloatIntConv and DoubleLongConv usage lead to undefined behaviours due to type aliasing violations. The conformed way is to implement a bit cast using memcpy.
jlong_accessor usage leads to undefined behaviours due to reading from inactive members of unions. While type punning is legal in C, it is not in C++, and may break in the future. Using a struct combined with memcpy would be sufficient here.
