Embedded SOLR - Commit issue

[Sunny Bassan]

I have implemented the embedded SOLR approach for indexing of database
records. I am indexing approximately 10 millions records, querying and
indexing 20,000 records at a time. Each record is added to the
updateHandler via the updateHandler.addDoc() function once all 20,000
records have been added a commit() call is made. Issue is that after
this commit call I don't see any changes to the index. Even after an
optimize call, which is called after all records have been added to the
index, I don't see any changes to the index. In order to see changes I
have to manually bounce the SOLR webapp in Tomcat. Is this the designed
functionality? If not what can I do in order to see changes after commit
calls are made? Thanks.
 
Running SOLR and the embedded SOLR Java app on a Windows XP machine.
 
Commit and optimize calls:
 
    private static void commit() throws IOException 
    {
        commit(false);
    }
 
    private static void optimize() throws IOException 
    {
        commit(true);
    }
    
    private static void commit(boolean optimize) throws IOException 
    {
        UpdateHandler updateHandler = core.getUpdateHandler();
        CommitUpdateCommand commitcmd = new
CommitUpdateCommand(optimize);
        updateHandler.commit(commitcmd);
    }
