    Description

      trait T {
          abstract def foo(a, b = 1)
      }
      
      T t = { o1, o2 ->
          println o1
          assert o2 == 1
      }
      t.foo(42) // Caught: groovy.lang.MissingMethodException: No signature of method: abstractMethod$_run_closure1.doCall() is applicable for argument types: (java.lang.Integer) values: [42]
      

      Expected result: it should just work or throw GroovyCastException in case of traits are not SAM candidates
