System.setSecurityManagerDirect looks a bit ugly now. Can this be renamed to implSetSecurityManager and avoid the line break in the  middle of the declaration?

The usage of System.err usage in setSecurityManager also needs to be re-examined as this will run arbitrary code when System.err can be changed. To fix this will require capturing the stream at startup (as was done with the illegal access logger). It's okay to integrate with what you have for the first push and we can fix this issue with System.err when the warning message is changed to the intended message.
