    Preondition Violations
    Expression context.assignInstanceVariable(instAsgnNode.getName()) cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression context.retrieveClassVariable(classVarNode.getName()) cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression context.assignInstanceVariable(instAsgnNode.getName()) is a void method call, and thus it cannot be parameterized
    Expression context.retrieveClassVariable(classVarNode.getName()) is a void method call, and thus it cannot be parameterized
    Expression instAsgnNode cannot be unified with expression classVarNode , because common superclass org.jruby.ast.Node does not declare member(s) public java.lang.String getName()
