Why doesn't Java have optimization for tail-recursion at all? [duplicate]

This question already has an answer here:

• What limitations does the JVM impose on tail-call optimization 4 answers

From what I have read: The reason is because it is not easy to determine which method will actually be called as we have inheritance.

However, why doesn't Java at least have tail-recursion optimization for static methods and enforce proper way to call static methods with the compiler? Why Java has no support at all for tail-recursion.

I am not sure if there is any difficulty here at all.
