WrapLog 1.2 released

This release adds template based logging, for example:

logger.info("{} is {} years old", name, new Integer(age));

This allows to get rid of "if logger.isInfoEnabled()" code without taking a performance hit.

Furthermore it is now possible to specify a error handler for messages that cannot be logged because for example the disk with the log file became full. The default handler throws a LoggingException (like version 1.1 did).
