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.
