If you want to modify an existing Jetty XML file, you need to copy it from $JETTY_HOME/etc to $JETTY_BASE/etc and then modify the $JETTY_BASE/etc XML file. Of course, for that XML file to be considered, the correspondent module should be enabled. If you are writing a custom module, then your custom XML file needs to be in $JETTY_BASE/etc. If you have done the above and my.property does not work, then seems like a bug.
