----------------------------------------------------
Beats me. I imported the repo into Eclipse and it doesn't built (as said
above).

I imported it into IntelliJ (which I normally do not use). I did so by opening
the repo folder in IntelliJ and importing the project as a Maven project.
Then I went to the {{LoggerTest}} class and tried running the
{{debugWithParams}} test method. Then I am greeted with lots of errors as well:

> I have the feeling that this code below from the Log4jLogger class has a bug.
> I believe the intention of the code is to use the throwable extracted from
> the message params of the parametrized message if the {{throwable}} parameter
> was not explicitly provided to the method. But to accomplish this, the
> condition would need to be {{if (throwable == null)}} in the code snippet
> below. This seems to cause exception stack traces to be swallowed if the
> throwable is only provided in the params array but not explicitly in the
> {{throwable}} argument.
> {code}
> public void log(final Marker marker, final String fqcn, final int level,
> final String message, final Object[] params, Throwable throwable) {
> ...
> msg = new ParameterizedMessage(message, params, throwable);
> if (throwable != null) { // I am pretty sure the idea was to use a "=="
> here and not a "!="
> throwable = msg.getThrowable();
> }
> ...
> }
> {code}
