[jira] Created: (JAMES-318) java.lang.NullPointerException when host is unknown
Message:
A new issue has been created in JIRA.

Here is an overview of the issue:
---------------------------------------------------------------------
Key: JAMES-318
Summary: java.lang.NullPointerException when host is unknown
Type: Bug
Status: Unassigned
Priority: Major
Project: James
Components:
Remote Delivery
Versions:
2.2.0
Assignee:
Reporter: Hes Siemelink
Created: Wed, 18 Aug 2004 5:44 AM
Updated: Wed, 18 Aug 2004 5:44 AM
Description:
I encountered the following NullPointerException:
18/08/04 14:29:59 INFO James.Mailet : RemoteDelivery: Unknown gateway host: unknown host
18/08/04 14:29:59 INFO James.Mailet : RemoteDelivery: This could be a DNS server error or configuration error.
18/08/04 14:29:59 INFO James.Mailet : RemoteDelivery: Exception caught in RemoteDelivery.run()
java.lang.NullPointerException
at org.apache.james.transport.mailets.RemoteDelivery.deliver(RemoteDelivery.java:409)
at org.apache.james.transport.mailets.RemoteDelivery.run(RemoteDelivery.java:912)
at java.lang.Thread.run(Thread.java:534)
This is caused by logging information about a HostAddress that happens to be null.
The HostAddress is null because I had a misconfiguration in my config.xml: a gateway server that could not be found.
I fixed the issue for myself by entering the correct host name.
Still, NullPointerExceptions are a bad sign.
Also, the message seems to disappear from the queue. I can't find it in the spool directory and there is no attempt of delivery after a restart.
In other words, I seem to observe that a message gets lost when this occurs.

[jira] Commented: (JAMES-318) java.lang.NullPointerException when host is unknown

Body:
Messages do get lost when this occurs.
Looking at the exception handling in RemoteDelivery.run() it makes sense, but I think it is unwanted behavior.
I think the best way to solve this is to explicitly check for null:
In RemoteDelivery.deliver(), add the following
while ( targetServers.hasNext()) {
try {
HostAddress outgoingMailServer = (HostAddress) targetServers.next();
// line 409:
+ if (outgoingMailServer == null) {
+ continue;
+ }
StringBuffer logMessageBuffer =
new StringBuffer(256)
.append("Attempting delivery of ")
.append(mail.getName())
.append(" to host ")
.append(outgoingMailServer.getHostName())
.append(" at ")
.append(outgoingMailServer.getHost())
.append(" to addresses ")
.append(Arrays.asList(addr));
log(logMessageBuffer.toString());
(Sorry, don't have time now to setup cvs/diff/patch)

Body:
There is a different fix for this in CVS. It matches the fix already made for the same reason in the DNSServer code. The iterator really should not return true if it won't be able to return a valid HostAddress.
This fix will be present in a test build posted tonight. Please test and let us know if it takes care of the problem in your environment.

This bug was identical to JAMES-236, except for being in the gateway server iterator instead of the MX hosts iterator in the DNSServer code.
