Make logging on Tomcat use JDK14LoggerPlugin by default
-------------------------------------------------------

                 Key: MODCLUSTER-185
                 URL: https://jira.jboss.org/browse/MODCLUSTER-185
             Project: mod_cluster
          Issue Type: Feature Request
    Affects Versions: 1.1.0.Final
         Environment: Windows 7 x64, Java 1.6.0_18-b07 32bit, Tomcat 6.0.29 + APR 1.1.20 + load-demo webapp
jboss-logging-jdk.jar Implementation-Version: 2.1.1.GA
jboss-logging-spi.jar Implementation-Version: 2.0.5.GA
            Reporter: Ruslan Gainutdinov
            Assignee: Jean-Frederic Clere


I`ve added 
jboss-logging-jdk.jar
jboss-logging-spi.jar
mod_cluster.jar
to Tomcat lib/ directory.

However, when I start Tomcat, no messages from mod_cluster is displayed.
By debugging I was able to understand what NullLoggerPlugin is used.

Where is a code to initialize logging in Tomcat - org.jboss.modcluster.catalina.ModClusterListener.java:65
however, it is not working because org.jboss.logging.Logger.init() called before it.
By default, system tries to load log4j plugin, which is not available in this environment.
After that, it sets NullLoggerPlugin.

To workaround this, I have added -Dorg.jboss.logging.Logger.pluginClass=org.jboss.logging.jdk.JDK14LoggerPlugin
to java options used when Tomcat is started.

I propose fixing org.jboss.modcluster.catalina.ModClusterListener.java with patch (attaching in next comment).
