A java logging Handler that delegates to a Ruby logger. The name of the j.u.l. logger is used as the progname argument to Logger.add.

The translation between j.u.l. serverity levels and Ruby Logger levels isn’t exact.

Class Method Details

.create(logger) ⇒ Object

NOTE: Since this class overrides a Java class, we have to use the Java constructor and set the logger after instantiation. (Overriding in JRuby is weird). Use this method to create a new logger that delegates to the passed logger.
