Unreleased 2.3 version of IndexWriter.optimize()  consistly throws java.lang.IllegalArgumentException
out-of-the-box
--------------------------------------------------------------------------------------------------------------------

                 Key: LUCENE-1036
                 URL: https://issues.apache.org/jira/browse/LUCENE-1036
             Project: Lucene - Java
          Issue Type: Bug
          Components: Index
    Affects Versions: 2.3
         Environment: AIX 5.3 Unix, Java 1.4,  lucene-core-2007-10-26_03-16-46.jar
            Reporter: R Giles


Since the upcoming 2.3 version of Lucene has support for the setRAMBufferSizeMB() method in
Index Writer,  I thought I would test its performance.   So, using my application that was
built upon (and worked with) Lucene 2.2,  I downloaded the nightly build 2007-10-26_03-16-46
and rebuilt my application with new code setting setRAMBufferSizeMB() from a properties file.
  My test data resides in a database table of 30 columns holding 1.25 million records.   The
good news is that performance is superior to Lucene 2.2.  The indexing completes in roughly
1/3 the time.   The bad news is the Index Writer.optimize() step now throws an java.lang.IllegalArgumentException.
I also run tests against various other tables.  Indexing smaller amounts of data did not throw
the exception.  Indexing largers amounts of data did throw the exception.  Note, I also tested
nightly builds dating back to 2007-10-05.
