-----------------------------------

             Summary: NPE in StaticVerifier
                 Key: GROOVY-8959
                 URL: https://issues.apache.org/jira/browse/GROOVY-8959
             Project: Groovy
          Issue Type: Bug
          Components: Compiler
    Affects Versions: 2.5.5, 2.4.16
            Reporter: Eric Milles


I don't have the exact code that created this error, but the fix seems pretty simple.

{code:java}
// excerpt from StaticVerifier.visitConstructorOrMethod
                        public void visitVariableExpression(VariableExpression ve) {
                            if (exceptions.contains(ve.getName())) return;
                            /* GRECLIPSE edit -- VariableExpression.isInStaticContext is null safe
                            Variable av = ve.getAccessedVariable();
                            if (av instanceof DynamicVariable || !av.isInStaticContext()) {
                            */
                            if (ve.getAccessedVariable() instanceof DynamicVariable || !ve.isInStaticContext()) {
                            // GRECLIPSE end
                                addVariableError(ve);
                            }
                        }
{code}
