Scott Lewis commented on AMQ-2256:
----------------------------------
The String path passed to the API at
org.apache.activemq.transport.tcp.TcpTransportFactory.createTransport(TcpTransportFactory.java:125)
is "/exampleTopic". The exact contents of the string doesn't matter.
> Unnecessary TcpTransportFactory NumberFormatException and warning

> Project: ActiveMQ
> Issue Type: Bug
> Components: Transport
> Affects Versions: 5.2.0
> Environment: Windows XP
> Reporter: Scott Lewis
>
> When executing TcpTransportFactory.createTransport(URI location, WireFormat
> wf) the following warning is incorrectly generated:
> WARNING: path isn't a valid local location for TcpTransport to use
> java.lang.NumberFormatException: For input string: "/exampleTopic"

> With the topic name set to "/exampleTopic"
> The code responsible for this looks like:
> URI localLocation = null;
> String path = location.getPath();
> // see if the path is a local URI location
> if (path != null && path.length() > 0) {
> int localPortIndex = path.indexOf(':');
> try {
> Integer.parseInt(path.substring(localPortIndex + 1,
> path.length()));
> String localString = location.getScheme() + ":/" + path;
> localLocation = new URI(localString);
> } catch (Exception e) {
> LOG.warn("path isn't a valid local location for TcpTransport
> to use", e);
> }
> }
> SocketFactory socketFactory = createSocketFactory();
> return createTcpTransport(wf, socketFactory, location, localLocation);
> }
> The problem seems to be that for the path="/exampleTopic", the following line:
> int localPortIndex = path.indexOf(':');
> returns -1 (no colon and no port specified in path
> and the subsequent line:
> Integer.parseInt(path.substring(localPortIndex + 1,
> path.length()));
>
> generates the NumberFormatException (because the path does not have any
> integer).
> It seems that perhaps there should be some test like:
> if (localPortIndex != -1) {
> ...
> }
> I will create a patch if desired. Just LMK.
