[patch] Fix ApacheDS code to allow control and reduce number of outputted logs

      I am using Maven artifact apacheds-all version 2.0.0-M10 (http://mvnrepository.com/artifact/org.apache.directory.server/apacheds-all/2.0.0-M10).

      I want to start and stop the server from my Java code (in a way similar to the one described in the official 'embedded sample': http://svn.apache.org/repos/asf/directory/documentation/samples/trunk/embedded-sample/src/main/java/org/apache/directory/seserver/EmbeddedADSVer157.java).

      The problem is: ApacheDS start takes 7 minutes and recuces to 3 seconds when standard output is redirected to /dev/null. Reason: you make lots of debug-level logging which take 99.9% of the startup time.

      I would like to restrict logging from ApacheDS to ERROR level. However, it is not possible because of the flawed ApacheDS code.

      You use SLF4J loggers this way:
      private static final Logger LOG = LoggerFactory.getLogger( JdbmIndex.class.getSimpleName() );

      This is absolutely unacceptable. The result of this code that the logger would be created for name 'JdbmIndex' and there is no way to use logger inheritance to control all logging from ApacheDS code, without affecting my own code. I don't want to look through ApacheDS code, find classes that fail to use logging correctly and silence each of these classes one by one in my own logging configuration.

      The correct way for using logging in Java is to use:
      private static final Logger LOG = LoggerFactory.getLogger( JdbmIndex.class );

      Then the logger would be created for name 'org.apache.directory.server.core.partition.impl.btree.jdbm.JdbmIndex' and I would be able to silence the whole 'org.apache.directory' or just 'org.apache.directory.server.core.partition' - or any part I like.

      I created a patch based on the today version of trunk. It introduces a single correct way of creating loggers across all ApacheDS code. I have also updated your logging configuration in log4j.properties to make sure the application behaviour won't change after my fixes.
