Re: 2.6 is not source compatible with 2.5

Sun, 29 May 2016 13:42:24 -0700

Here is the text that I propose to add to the announcement. I would also add something similar to the web site.

Note that subsequent to the release a minor source incompatibility was found due to the addition of new methods to
the Logger interface. If you have code that does:

logger.error(null, “This is the log message”, throwable);

or similar with any log level you will get a compiler error saying the reference is ambiguous.  To correct this either do:

logger.error(“This is the log message”, throwable);

or 

logger.error((Marker) null, “This is the log message”, throwable);

Yet another reason to hate null! ;)

When you pass null as the first argument it doesn't know which is better

Wait, how are error(Marker, String, Object) and error(String, Object, Object) even confused by the compiler?

Only if the compatibility issue can be fixed. I don't think it can. We will just update the site and announcement.

So what do we do, follow up with 2.6.1 right away?

Can’t do that. That would require a re-release.

Speaking of which, the archives directory only lists a couple of releases. I thought they were all supposed to be there.

I think the RELEASE-NOTES.txt in the dist area needs to be updated as well.

I will add something to the announcement text when I send out the emails.  Those will go out in a few hours.

We are going to need to update the release notes and/or site for 2.6 to note that the 2.6 is not source compatible with previous releases. I tested going from 2.5 to 2.6 at work and got:

[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] /E:/vcs/svn/...XYZ..:[155,15] reference to error is ambiguous
  both method error(org.apache.logging.log4j.Marker,java.lang.String,java.lang.Object) in org.apache.logging.log4j.Logger and method error(java.lang.String,java.lang.Object,java.lang.Object) in org.apache.logging.log4j.Logger match

[INFO] 2 errors

with source code like:

    public void xyz(final String message, final Throwable t) {
        ...
        logger.error(null, message, t);
        ...
        logger.trace(null, message, t);
        ...
    }

Next time, I'll remember to test with a "real" client.
