Compilation Error

Explanation

Both methods m (int ... a), and m (Integer ... a) can be applied for an m (1,2) method call. None of these methods is the most specific one, so there a compiletime error will occur (an ambiguous methods).
PS: Earlier versions of JDK8 contained an error, due to which the given code successfully compiled contrary to specifications.
