Beta 4, is slf4j bindings broken?
Hi,
When I try to use SLF4J bindings with log4j2.0 implementations I run into
the following exception?

This is an slf4j jar. Download the jar from http://www.slf4j.org/download.html. Or add
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-ext</artifactId>
<version>1.7.2</version>
</dependency>
to your maven pom.

Ralph,
Can you point me how to build this jar by myself, so that I do not need to
wait for the next available build.
Thanks

The SLF4J binding also supports the SLF4J extensions and so requires slf4j-ext-1.7.2.jar. Please create a Jira issue to have that library be made optional.

Are you including the slf4j-ext jar in addition to the slf4j-api jar?
