Thilo Goetz reopened UIMA-1352:
-------------------------------
As Marshall discovered, this fix breaks other code. The issue is that
different parts of our code make different assumptions about how the findKey()
method in the index implementations is supposed to work. The code that is now
broken assumes that findKey() returns a node in the index tree, while the code
that was broken before assumes it returns a key. Because both are ints, this
difference in interpretation does not cause a compile error and only shows up
at runtime.
> java.lang.ClassCastException using find() with a SET index

> 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 !!!!
> ...
> }
