Hi Ceki,

Thanks - I will update our nlog4j dependency and test it out. I will let you know how I go.

Cheers,
Nick

Nick,

This problem has been already reported a few days ago. Nevertheless, thank you for reporting it.

As you observe, nlog4j admits a String instead of an object in its printing methods.

There is a known method for fixing this problem. You can expect it to be fixed in a few hours.

Hi,

We recently added nlog4j-1.2.14 as the logging mechanism for Apache Directory Server.

I've been developing another library, called Atlassian User, which includes ApacheDS, and all of its dependencies. I have recently begun to integrate Atlassian User with another application, which uses log4j-1.2.8 .

When working on the integration within IDEA I encounter NoSuchMethodError(s) on simple logging statements which *only* use a String as an argument to the logger (e.g. log.debug("example message" + exception.getMessage()):

java.lang.NoSuchMethodError: org.apache.log4j.Logger.debug(Ljava/lang/String;)V

I've looked at the source of nlog4j and log4j and I can see the slight difference in Category - nlog4j specifies a String, instead of an object, for methods such as debug(..), info(..), etc..

I've also written a quick test application which uses two classes - one dependent on log4j and one dependent on nlog4j. A runtime IncompatibleClassChangeError occurs:

Exception in thread "main" java.lang.IncompatibleClassChangeError

Can you please advise me as to how to overcome this problem? If nlog4j cannot work alongside log4j libraries then many pre-existing applications will not be able to use ApacheDS.

Cheers,
Nick
