> -------------------------
>
> Key: GROOVY-7709
> URL: https://issues.apache.org/jira/browse/GROOVY-7709
> Project: Groovy

>
> {code}
> interface Y extends GroovyObject {}
> def cl = {println 1} as Y
> assert cl instanceof GroovyObject
> if (cl) println "!cl"
> {code}
> the code above will cause the execution of the method getMetaClass in the boolean part of the "if". It looks like this code path now produces a NPE
> {code}
> java.lang.NullPointerException
