AssertionError on creating doc containing field with empty string as field name
-------------------------------------------------------------------------------
Key: LUCENE-1179
URL: https://issues.apache.org/jira/browse/LUCENE-1179
Project: Lucene - Java
Issue Type: Bug
Components: Index
Affects Versions: 2.3
Reporter: Michael McCandless
Assignee: Michael McCandless
Priority: Minor
Spinoff from here:
http://www.gossamer-threads.com/lists/lucene/java-user/58496
Pre-2.3 you were allowed to add Fields to a Document where the field name is
the empty string. In 2.3.0 it broke: you hit this during flush:
{code}
java.lang.AssertionError
at org.apache.lucene.index.TermInfosWriter.add(TermInfosWriter.java:143)
at
org.apache.lucene.index.DocumentsWriter.appendPostings(DocumentsWriter.java:2290)
at
org.apache.lucene.index.DocumentsWriter.writeSegment(DocumentsWriter.java:1985)
at org.apache.lucene.index.DocumentsWriter.flush(DocumentsWriter.java:539)
at org.apache.lucene.index.IndexWriter.doFlush(IndexWriter.java:2497)
at org.apache.lucene.index.IndexWriter.flush(IndexWriter.java:2397)
at org.apache.lucene.index.IndexWriter.closeInternal(IndexWriter.java:1204)
at org.apache.lucene.index.IndexWriter.close(IndexWriter.java:1178)
at org.apache.lucene.index.IndexWriter.close(IndexWriter.java:1153)
{code}
The bug is just an over-aggressive assert statement. I'll commit a fix shortly
& port to 2.3 branch for 2.3.1 release.
