there is documentation.
It describes everything what is available out-of-the-box, no more, no less.
So could you please finally make an effort to read it?
And documentation does not describe anything specific to "catalina.sh", because in JaCoCo there is simply nothing out-of-the dedicated explicitly to it.
Also by reading Tomcat documentation (
https://tomcat.apache.org/tomcat-8.0-doc/RUNNING.txt ) you will find that additional Java options such as "-javaagent" (exactly like other Java options such as "-Xmx") can be specified via environment variable CATALINA_OPTS
Last but not least - before asking next question, please first spend more time than you do now on research by your own.
