18  * Since java 1.4 there is a Logger implemented in java itself, if you have code which requests a
19  * java.util.logging.Logger object to which it will log to, and you want it to log the MMBase logger
20  * then, you can offer it an instance of this class, which wraps an MMBase Logger object in a
21  * java.util.logging.Logger object.
22  *
23  * For the correspondence between levels of java logging and mmbase logging see javadoc of
24  * {@link org.mmbase.util.logging.java.Impl}.
