    Description

      interface Y extends GroovyObject {}
def cl = {println 1} as Y
assert cl instanceof GroovyObject
if (cl) println "!cl"

      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

      java.lang.NullPointerException
