Paul Elschot commented on LUCENE-1432:
--------------------------------------
I think this is a duplicate of LUCENE-1459, for which the better fix than the patch here was just committed.

> We recently upgraded from Lucene 2.3.1 to 2.4.0.
> We left the code as-is apart from the needed changes to the package name for snowball, everything seems to run as before... Until yesterday when we started noticing the following stacktrace:
> java.lang.ClassCastException: java.util.BitSet cannot be cast to org.apache.lucene.search.DocIdSet
> org.apache.lucene.search.CachingWrapperFilter.getDocIdSet(CachingWrapperFilter.java:76)
> org.apache.lucene.misc.ChainedFilter.getDocIdSet(ChainedFilter.java:200)
> org.apache.lucene.misc.ChainedFilter.getDocIdSet(ChainedFilter.java:145)
> org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:140)
> org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:112)
> org.apache.lucene.search.Searcher.search(Searcher.java:136)
> Our index is 15gb in size and was made with Lucene 2.4.0.
> The index holds around 36 million (Lucene) documents and 268 million terms.
