Yes.

These can be any system property value, including those passed with -D
on the java command line (use create-jvm-options to set) and system
properties (use create-system-properties to set).
Also, these substitutions can be nested in a string, so you can do:
value="some ${abc} string ${def}"
where abc and def are system properties.
