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

             Summary: SC: Lambda within lambda that references "this" produces cast exceptions
                 Key: GROOVY-9341
                 URL: https://issues.apache.org/jira/browse/GROOVY-9341
             Project: Groovy
          Issue Type: Bug
            Reporter: Eric Milles


Follow up to GROOVY-9332 and GROOVY-9333.  Consider the following:
{code:groovy}
@groovy.transform.CompileStatic
class ThisTest {
  private final ThisTest that = this

  void m() {
    java.util.function.Predicate<ThisTest> p1 = (ThisTest t1) -> {
      java.util.function.Predicate<ThisTest> p2 = (ThisTest t2) -> {
        assert this === t1 && this === t2
      }
      p2.test(t1)
    }
    p1.test(that)
    p1.test(this)
  }
}
new ThisTest().m()
{code}

{code}
java.lang.ClassCastException: ThisTest$_m_lambda1 cannot be cast to ThisTest
        at ThisTest$_m_lambda1$_lambda2.doCall(TestScript4.groovy:9)
        at ThisTest$_m_lambda1.doCall(TestScript4.groovy:11)
        at ThisTest.m(TestScript4.groovy:13)
        at ThisTest$m.call(Unknown Source)
{code}
