-----------------------------------------
Assignee: Jean-Baptiste Onofré
> FailoverTransport throws UnknowHostException on compareURIs
> -----------------------------------------------------------
>
> Key: AMQ-9438
> URL: https://issues.apache.org/jira/browse/AMQ-9438
> Project: ActiveMQ Classic
> Issue Type: Improvement
> Components: Transport
> Affects Versions: 5.18.3, 5.17.6, 5.16.7
> Environment: This occurs using OpenJDK 11 on both Windows and Linux
> environments.
> Reporter: George McCone
> Assignee: Jean-Baptiste Onofré
> Priority: Minor
>
> In the
> org.apache.activemq.transport.failover.FailoverTransport.compareURIs(), it is
> trying to compare 2 hosts to see if they are the same.
> To accomplish this, the function InetAddress.getByName() used to help extract
> out the the IP address of each of the hosts to see if they are the same.
> In the event one of the hosts is not resolvable, InetAddress.getByName()
> throws a UnknownHostException.
> This UnknownHostException is not being caught in the try/catch block, only
> IOException.
> I believe the exception catch block should be extended to catch
> UnknownHostException as it is simply doing a string compare that the 2 hosts
> are the same at that point.
> For example, in the stacktrace below the uri was,
> failover:(tcp://UNKNOWN:61616,tcp://AMQ1:61616)?randomize=false/org.apache.activemq.jndi.ActiveMQInitialContextFactory/ConnectionFactory
> {code:java}
> java.net.UnknownHostException: No such host is known (UNKNOWN)
