Description

My file "ite.groovy":

import groovy.transform.TypeChecked
interface A {}
@TypeChecked
trait B implements A {
  def foo() {
    bar()
  }
}
class C implements B {}
println new C().foo()

Fails to compile (as it should) but does not give a helpful error message:

$ groovy ite.groovy 
Caught: BUG! exception in phase 'instruction selection' in source unit '<my path>/ite.groovy' ClassNode#getTypeClass for A called before the type class is set
BUG! exception in phase 'instruction selection' in source unit '<my path>/ite.groovy' ClassNode#getTypeClass for A called before the type class is set

Remove the @TypeChecked and it gives a coherent and useful error.
