[security-dev 01396]: Ending support for Java 1.1 policy files

[Vincent Ryan]

Hello all,

More than 11 years ago we introduced a new format for Java policy files
in Java 1.2. We deprecated but retained support for the old Java 1.1
format. I'd like to propose that we now remove support for that legacy
format.

This would allow us to eliminate several hard-coded dependencies on a
set of classes which were deprecated long ago. The change would form
part of our JDK modularization effort.

Thanks.
