Description

It is very commonly the case when using the object translator that the object must be assignable to a particular interface (or extend a particular class). In most cases, the value obtained will be injected into a property of an object and a ClassCastException will occur that will (hopefully) identify the invalid contribution.

In some cases, the object may go into some form of untyped collection, causing a class cast exception at a later point.

It would be nice if the object translator could enforce an assignability check directly, ie.

<attribute name="object" translator="object:java.lang.Runnable"/>
