Jane,
Thank you, escaping the key/value in that way addressed the issue of
being able to get the property into the system.
I will read further on Kedar's blog when he gets a chance to propose how
one might implement the property to actually be read as a JVM argument.
Thanks again,
Andrew

Hi Andrew,
Can you try the following asadmin syntax:
asadmin.bat create-system-properties --user admin --host localhost
--port 4848 --target instance-one --
-Dframework.propertyregistry.override=file\\:///path/to/file
The "--" is to separate the options and the operand. Also, you need to
escape the ":" since it is used as a separator for multiple properties.
HTH,
Jane
