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

             Summary: ComposedClosure thrown ClassCastException when owner is not Closure
                 Key: GROOVY-10083
                 URL: https://issues.apache.org/jira/browse/GROOVY-10083

          Issue Type: Bug
          Components: groovy-runtime
    Affects Versions: 2.5.14

ComposedClosure consider owner is an instance of Closure, But If we changed owner property to other class, setResolveStrategy will thrown ClassCastException.

This is a simple test
{code:java}
a = {println "aa"}
b = {println "bb"} >> a
c = 1
d = b.rehydrate(c,c,c)
d.setResolveStrategy(Closure.DELEGATE_FIRST)
// ERROR java.lang.ClassCastException:
// java.lang.Integer cannot be cast to groovy.lang.Closure

{code}
