Concurrent DynamicPolicy

[Peter Firmstone <ji...@zeus.net.au>]

Well,

I've just done some significant refactoring and have plugged in the SPI 
implementation for ConcurrentDynamicPolicyProvider as a concurrent 
replacement for DynamicPolicyProvider after some initial bug fixes 
during testing, it appears to now be executing properly.

No performance tests yet I'm afraid.

Actually the implementation is broken down into two parts, one a 
ConcurrentPolicyFile implementation, that replaces Java's inbuilt 
PolicyFile for use as a base policy for 
net.jini.security.policy.PolicyFileProvider.

The second the ConcurrentDynamicPolicyProvider that utilises 
net.jini.security.policy.PolicyFileProvider as it's base policy.

Combining these three Policy Providers, creates a very concurrent 
implementation.

However there is a new feature that's been included as well, that allows 
us to dynamically revoke permissions as well.  I'll explain it's 
implementation in another installment.

For now I need some volunteers, to run the new implementation through 
it's paces.  Gregg, are you able to test if this solves your original 
problem?

N.B. I haven't committed the changes just yet, will do so tomorrow morning.

Regards,

Peter.
