Answer 1

Looks like it's related to bug #6886431, which seems to be fixed in OpenJDK 7.

Below is the bug description,

Bug Description:

When invoking a method with the following overloaded signatures, I expect an ambiguity error (assuming the arguments are compatible with both):

int f(Object... args);
int f(int... args);

javac treats the second as more specific than the first. This behavior is sensible (I prefer it), but is inconsistent with the JLS (15.12.2).
