Subject ClassCastException/DocumentWriter and NullPointerException/RAMInputStream
Date Wed, 21 Feb 2007 22:03:25 GMT
When adding documents to an index has anyone seen either

java.lang.ClassCastException: org.apache.lucene.analysis.Token cannot be cast to 
org.apache.lucene.index.Posting
   at 
org.apache.lucene.index.DocumentWriter.sortPostingTable(DocumentWriter.java:238)
   at org.apache.lucene.index.DocumentWriter.addDocument(DocumentWriter.java:96)
   at org.apache.lucene.index.IndexWriter.addDocument(IndexWriter.java:476)

or

java.lang.NullPointerException
   at org.apache.lucene.store.RAMInputStream.<init>(RAMInputStream.java:32)
   at org.apache.lucene.store.RAMDirectory.openInput(RAMDirectory.java:171)
   at org.apache.lucene.index.SegmentReader.initialize(SegmentReader.java:155)
   at org.apache.lucene.index.SegmentReader.get(SegmentReader.java:129)
   at org.apache.lucene.index.SegmentReader.get(SegmentReader.java:110)
   at org.apache.lucene.index.IndexWriter.mergeSegments(IndexWriter.java:702)
   at org.apache.lucene.index.IndexWriter.mergeSegments(IndexWriter.java:686)
   at org.apache.lucene.index.IndexWriter.flushRamSegments(IndexWriter.java:656)
   at org.apache.lucene.index.IndexWriter.close(IndexWriter.java:402)

This data has been indexed many times, but I've never seen this before.  It's 
Java 6 and Lucene 2.0.

Thanks
Antony
