Another possible persistence issue, maybe? @enebo

The fix for #4662 I thought would affect this but what it reads back is not being seen as a valid variable and this ends up violating some logic when the interpreter first interacts with it.

I marked this against 9.2 since we have 2 side branches changing our internals to be based on either (ByteList or RubySymbol - an ongoing discussion). What we have to date is pushing a ByteList through the parser. In the case of StaticScope we have a ByteList now so it will trivially fix this (although we may change this to a RubySymbol before all is said and done).

@enebo enebo modified the milestones: JRuby 9.1.11.0, JRuby 9.2.0.0 Jun 12, 2017
