/**
 * 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
* transport.threadName.
* For example:
*

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