DocumentCache changes - missing return statement

Vadim,

Looks like there was a missing return statement in this patch (code
for stored instance of String):

             return null;
         } else if (v instanceof Document) {
             return (Document) v;
+        } else if (v instanceof String) {
+            try {
+                Document doc = DOMParser.toDocument((String) v);
+                ((DBDocument) doc).setSource(new NodeSource(col, key));
+            } catch (Exception e) {
+                if (log.isWarnEnabled()) {
+                    log.warn("ignored exception", e);
+                }
+            }
         } else if (v instanceof byte[]) {
             try {
                 SymbolTable s = col.getSymbols();

Regards,
Natalia
