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

Pablo, remind me to buy you a beer next time I see you.  I found the bug, it's way down in the index implementation, where one int looks like any other.

> It is not possible to use the FSIndex.find() method when the indexing strategy is a SET.
> A java.lang.ClassCastException is thrown.
> For example:
> FSIndex idx = aJCas.getJFSIndexRepository().getIndex("idx_SET");
> while (doSomething) {
>    MyFeatureStructure myFs = new MyFeatureStructure(aJCas);
>    myFs.setMyFeature(value);
>    myFs.addToIndexes();
>  
>    // Try to recover from index    
>    MyFeatureStructure otherFs = (MyFeatureStructure)idx.find(myFs);  // ClassCastException !!!!
>    ...
> }
