As Kevin pointed out, $ROOTDIR is a part of jpackage's internal interface.
However the problem problem you face is because you use backslashes 
which a treated by jpackage as escape characters. This should work:
---
-Djava.security.policy=$ROOTDIR/app/all.policy
---
and this should work too:
---
-Djava.security.policy=$ROOTDIR\\app\\all.policy
---

On condition these strings don't go through any environment that does 
its own escape characters processing.

Hmm, I'm surprised of this error. What is the exact value of 
—java-options parameter? As I side note, I'd recommend putting each java 
option in a separate —java-options jpackage parameter. jpackage supports 
multiple —java-options on command line.
