[jira] Commented: (AMQ-841) NullPointerException when using
MasterConnector and specifying the broker name with space in it.
[ https://issues.apache.org/activemq/browse/AMQ-841?page=comments#action_37531 ]
Marlon Santos commented on AMQ-841:
-----------------------------------
Hi,
i had seen that the problem was when the URISyntaxException was catched, there was no actual value given to the vmConnectorURI so it stays null. I can create a patch for this but i dont know which is the best approach, because of some issues.
a) shutdown the broker gracefully and display a warn sign that the broker is shutting down because of invalid brokername
b) trim the starting and ending space, and change spaces in - between the brokername.

> Key: AMQ-841
> URL: https://issues.apache.org/activemq/browse/AMQ-841
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 4.0.1
> Environment: Linux, jdk1.5.0_06
> Reporter: Richard Wafer
> Priority: Minor
>
> I've got a hard time trying to figure out why I got a null pointer trying to use the Master/slave configuration for ActiveMQ.
> Finnally by looking at the code I've saw the following:
> In BrokerService.java
> public void initializeMasterConnector(URI remoteURI) throws Exception {
> ...
> URI localURI = getVmConnectorURI();
> ...
> }
> public URI getVmConnectorURI() {
> if (vmConnectorURI == null) {
> try {
> vmConnectorURI = new URI("vm://" + getBrokerName());
> }
> catch (URISyntaxException e) {
> }
> }
> return vmConnectorURI;
> }
> My problem is that I've specified a broker name with space in it "Slave Broker". So I the new URI() here throw a URISyntaxException that was badly absorb. And this leads to a null pointer at line:159 of TransportFactory.java.
> String scheme = location.getScheme(); when location is null du to the previous exception.
> The link between the error and the cause was not clear at the first sigth.
> A precondition on the setBrokerName could do the job.
