Description

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 !!!!
...
}
