[jira] Created: (AMQ-841) NullPointerException when using
MasterConnector and specifying the broker name with space in it.
NullPointerException when using MasterConnector and specifying the broker name with space in it.
------------------------------------------------------------------------------------------------
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.

-----------------------------------
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.
