# If specified, the Wrapper will be run as the specified user.
# IMPORTANT - Make sure that the user has the required privileges to write
# the PID file and wrapper.log files. Failure to be able to write the log
# file will cause the Wrapper to exit without any way to write out an error
# message.
# NOTE - This will set the user which is used to run the Wrapper as well as
# the JVM and is not useful in situations where a privileged resource or
# port needs to be allocated prior to the user being changed.
