| <p>A callin binding (<a href="s4.html" title="§4 Callin Binding" class="sect">§4</a>) may silently fail due to a <code>org.objectteams.LiftingFailedException</code>. |
| This exception will actually remain hidden because the callin binding is not explicitly invoked from any source code |
| but implicitly |
| by the runtime dispatch mechanism. To signal this situation the compiler raises an error against such callin binding. |
| |
| </p> |
| <p>However, the compiler should allow to configure this error and understand the warning token <code>"hidden-lifting-problem"</code> |
| for suppressing this problem. If the problem is ignored/suppressed and if at runtime the lifting problem occurs, |
| triggering of the callin binding will silently fail, i.e., the program will continue in this situation as if the binding |
| hadn't existed in the first place. |
