> Key: GROOVY-7558
> URL: https://issues.apache.org/jira/browse/GROOVY-7558
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 2.4.4
> Environment: Linux x86-64 / java 1.8.0_60
> Reporter: Jon Keys
> Assignee: Shil Sinha

> Originally posted on SO here: http://stackoverflow.com/questions/32212260/in-groovy-is-it-legal-to-reference-private-member-variables-from-within-a-closur
> The code below fails with {{java.lang.ClassCastException: Test$_doStuff_closure1 cannot be cast to Test}}. Interestingly, if I remove the {{@CompileStatic}} annotation or make the member variable non-private it works as expected.
> {code:java}
> class Test {
> private String str = "hi"
> @groovy.transform.CompileStatic
> public void doStuff() {
> Closure c = {
> println str
> }
> c()
> }
> }
> new Test().doStuff()
> {code}
> It also works when {{@CompileStatic}} is moved up to the class level
> {code:java}
> @groovy.transform.CompileStatic
> class Test {
> private String str = "hi"
> public void doStuff() {
> Closure c = {
> println str
> }
> c()
> }
> }
> new Test().doStuff()
> {code}
