Hi [~sstults], thanks for reuploading this. I am getting ClassCastException's for many tests when I attempt to run the test suite on the module.
The Exception is raised at the following line within LuceneStore#put method
{color:red}
data = IOUtils.serialize( datumWriter, fieldSchema, (T) v);
{color}
{code:title=LuceneStore.java|borderStyle=solid}
+  @Override
+  public void put(K key, T persistent) {
+    Schema schema = persistent.getSchema();
+    Document doc = new Document();
+
+    // populate the doc
+    List<org.apache.avro.Schema.Field> fields = schema.getFields();
+    for ( org.apache.avro.Schema.Field field : fields ) {
+      if (!persistent.isDirty( field.name() )) {
+        continue;
+      }
+      String sf = mapping.getLuceneField( field.name() );
+      if ( sf == null ) {
+        continue;
+      }
+      Schema fieldSchema = field.schema();
+      Object v = persistent.get( field.pos() );
