Description

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.
