org.jruby.runtime.scope.DummyDynamicScope

public class DummyDynamicScope
extends NoVarsDynamicScope

This is a DynamicScope that does not support any variables. It differs from NoVarsDynamicScope in that it has hard failures for "backref" and "lastline" accesses, since in the JRuby 1.3 cycle it was discovered that threads were sharing a single dummyscope while still setting per-call backrefs. The hard errors here are an attempt to catch such situations in the future, before the optimizing compiler work makes such determinations in advance.
