Primitive types and
java.*
class types are very commonly used and there is a limited number of them. Therefore, we can intern them safely (growth of the interning cache is naturally bounded) and improve allocation rate significantly.Further, this commit removes all calls to
Objects.hash()
, because each call allocates an array. It is especially useless when called with just one element.Co-authored-by: Guillaume Smet guillaume.smet@gmail.com
