By default, the Wrapper will log warnings about any missing classpath elements at the
DEBUG log level. It is fairly common to
want to see these generated log messages without also enabling all of the debug
output. This property makes it possible to specify the log level at which
the warnings will be logged.
Valid property values include:
: to log at the FATAL log level.
: to log at the ERROR log level.
: to log at the WARN log level.
: to log at the STATUS log level.
: to log at the INFO log level.
: to log at the DEBUG log level.
: to never log.
The default value is DEBUG.
If your application often has missing jars, then setting this value to NONE will disable warnings at any log level.
Classpath elements which are defined as wildards will never result in a warning as they only find matching files which exist.
