Subject Re: Heads-up - Trying out Maven and git for the container.
Date Sun, 02 Jun 2013 04:58:20 GMT
Hi Greg,

I noticed while reading your docs, you've got a java policy parser planned, there's a parser
in org.apache.river.api.security (package private) that fully supports java policy file syntax,
including undocumented features, as well as PermissionGrant, which makes policy implementation
simpler, easier to implement and is also non blocking, so policy deadlock can be avoided.

The PolicyParser interface is public, to allow alternate parsers, such as xml, or encrypted
policy files.

In future I also plan to implement a parser for OSGi syntax permission.perm in jar files as
previously discussed on the list.

Perhaps we might have some common use cases?
