Calling super() outside of a method causes NPE #4426
Description
run the attached project, tested with 9.1.6.0 and master branch.
jruby 9.1.6.0:
LoadError: load error: b -- java.lang.NullPointerException: null
require at org/jruby/RubyKernel.java:959
<main> at run.rb:5
plain ruby:
NoMethodError: super: no superclass method `' for Foo:Class
method_missing at org/jruby/RubyBasicObject.java:1655
<class:Foo> at foo.rb:2
<main> at foo.rb:1
Workaround: don't call super within the class body :)
