+/**
+ * The thread name filter, modifies the name of the thread during the invocation to a transport.
+ * It appends the remote address, so that a call stuck in a transport method such as socketWrite0
+ * will have the destination information in the thread name.
+ * This is extremely useful for thread dumps when debugging.
+ * To enable this transport, in the transport URI, simpley add<br/>
+ * <code>transport.threadName</code>.<br/>
+ * For example:</br>
+ * <pre><code>
+ * &lt;transportConnector 
+ *     name=&quot;tcp1&quot; 
+ *     uri=&quot;tcp://127.0.0.1:61616?transport.soTimeout=10000&amp;transport.threadName"
+ * /&gt;
+ * </code></pre>
