    What method is called when several could qualify is defined in the JLS #15.2.2:

    The first phase (§15.12.2.2) performs overload resolution without permitting boxing or unboxing conversion, or the use of variable arity method invocation. If no applicable method is found during this phase then processing continues to the second phase.

    The second phase (§15.12.2.3) performs overload resolution while allowing boxing and unboxing, but still precludes the use of variable arity method invocation. If no applicable method is found during this phase then processing continues to the third phase.

    The third phase (§15.12.2.4) allows overloading to be combined with variable arity methods, boxing, and unboxing.

    So in summary: widening > boxing&unboxing > varargs
