NullPointerException from FieldsReader after problem reading the index
----------------------------------------------------------------------

                 Key: LUCENE-1262
                 URL: https://issues.apache.org/jira/browse/LUCENE-1262
             Project: Lucene - Java
          Issue Type: Bug
          Components: Index
    Affects Versions: 2.3.1
            Reporter: Trejkaz


There is a situation where there is an IOException reading from Hits, and then the next time
you get a NullPointerException instead of an IOException.

Example stack traces:

java.io.IOException: The specified network name is no longer available
	at java.io.RandomAccessFile.readBytes(Native Method)
	at java.io.RandomAccessFile.read(RandomAccessFile.java:322)
	at org.apache.lucene.store.FSIndexInput.readInternal(FSDirectory.java:536)
	at org.apache.lucene.store.BufferedIndexInput.readBytes(BufferedIndexInput.java:74)
	at org.apache.lucene.index.CompoundFileReader$CSIndexInput.readInternal(CompoundFileReader.java:220)
	at org.apache.lucene.store.BufferedIndexInput.refill(BufferedIndexInput.java:93)
	at org.apache.lucene.store.BufferedIndexInput.readByte(BufferedIndexInput.java:34)
	at org.apache.lucene.store.IndexInput.readVInt(IndexInput.java:57)
	at org.apache.lucene.index.FieldsReader.doc(FieldsReader.java:88)
	at org.apache.lucene.index.SegmentReader.document(SegmentReader.java:344)
	at org.apache.lucene.index.IndexReader.document(IndexReader.java:368)
	at org.apache.lucene.search.IndexSearcher.doc(IndexSearcher.java:84)
	at org.apache.lucene.search.Hits.doc(Hits.java:104)

That error is fine.  The problem is the next call to doc generates:

java.lang.NullPointerException
	at org.apache.lucene.index.FieldsReader.getIndexType(FieldsReader.java:280)
	at org.apache.lucene.index.FieldsReader.addField(FieldsReader.java:216)
	at org.apache.lucene.index.FieldsReader.doc(FieldsReader.java:101)
	at org.apache.lucene.index.SegmentReader.document(SegmentReader.java:344)
	at org.apache.lucene.index.IndexReader.document(IndexReader.java:368)
	at org.apache.lucene.search.IndexSearcher.doc(IndexSearcher.java:84)
	at org.apache.lucene.search.Hits.doc(Hits.java:104)

Presumably FieldsReader is caching partially-initialised data somewhere.  I would normally
expect the exact same IOException to be thrown for subsequent calls to the method.
