checkArity confusingly raises line of outer caller for nested calls #5103

Environment

Provide at least:

• JRuby version: 9.1.13.0
• Mac OSX

Expected Behavior

I have code something like:

#Java interface
interface MyJavaInterface {
  void interfaceMethod(argItTakes)
}

#Ruby
class MyClass
  include org.example.MyJavaInterface

  # Note that we accidentally specify an extra arg here
  def interfaceMethod(argItTakes, extraArgThatIsAccident)
  end

  def someOtherMethod
    callJavaMethodThatInvokesAboveInterfaceMethodButWithOnlyOneArg
  end
end

Actual Behavior

JRuby generates an ArgumentError: wrong number of arguments (1 for 2) that points to the line in someOtherMethod, when the real error is that we implemented the interface incorrectly. The stack trace shouldn't filter out the java in this case, but do the full stack trace to expose this.
