/**
* 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>
* <transportConnector
* name="tcp1"
* uri="tcp://127.0.0.1:61616?transport.soTimeout=10000&transport.threadName"
* />
* </code></pre>
