Re: [equinox-dev] PermissionInfoCollection issues with perms cloning

Then you probably have your own way to populate your PermissionCollections. However in Equinox which supports the OSGi permission specifications, the way to populate the PermissionCollections is via PermissionInfos which require the "0,1,2" constructors.

If you have special permissions that cannot have those sort of constructors, then you can't use the OSGi permissions specifications and will need to customize a framework implementation to use your own permission management model.

PS: We were not loading our permissions from a standard policy file. Hence how we ended up with what we have.

Ok, I stand corrected. After looking at the code for PolicyParser it seems the 0, 1, 2 rule is indeed the case.

Other documentation seems to have implied that an arbitrary number of constructor arguments were acceptable:

http://docs.oracle.com/javase/6/docs/technotes/guides/security/crypto/CryptoSpec.html#AppA

However, I guess each of these different policy files must have it's own parser.

Sorry about my confusion.

Also, to be clear, there is no copying going on here. The code needs to construct a Permission object from the information in the PermissionInfo. The PermissionInfo contains the class name of the permission type with 0, 1 or 2 String arguments for the constructor. This very much the same as would be done by the Policy object to create permissions based upon the grant information in the policy file.
