The jakarta-commons-daemon-jsvc package includes jsvc, a service wrapper

also used the "-user" option to specify a user for it to run as, the
application correctly ran as that user but did not drop its increased
capabilities, allowing it access to all files and directories accessible to
the root user. (CVE-2011-2729)
