Description

Add this test to SolrExampleTests.java and it will fail when using the XML Request Writer (now default), but not if you change the SolrExampleJettyTest to use the BinaryRequestWriter.

 public void testAddDeleteInSameRequest() throws Exception {
    SolrServer server = getSolrServer();

    SolrInputDocument doc3 = new SolrInputDocument();
    doc3.addField( "id", "id3", 1.0f );
    doc3.addField( "name", "doc3", 1.0f );
    doc3.addField( "price", 10 );
    UpdateRequest up = new UpdateRequest();
    up.add( doc3 );
    up.deleteById("id001");
    up.setWaitFlush(false);
    up.setWaitSearcher(false);

    up.process( server );
  }

terminates with exception:
