If A method like:
override def foo(x: Object*)
overrides a Java method, it needs to be rewritten as:
def foo(x: Seq[Object])
override def foo(x: Array[Object]): Object = foo(Predef.wrapRefArray(x))
This should be handled by ElimRepeated but there were two bugs:
- `addVarArgsBridge` was called at phase `thisTransformer.next`, this is
too late to create the bridge since `T*` has already been rewritten as
`Seq[T]`
- The original method symbol needs to have the `override` flag dropped,
since it doesn't override anything.
Furthermore, RefChecks had to be moved after ElimRepeated, otherwise the
testcase would fail the overriding checks.
