New Revision: 1558828
URL: http://svn.apache.org/r1558828

Add an option to the Context to control the blocking of XML external entities
when parsing XML configuration files and enable this blocking by default when a
security manager is used. The block is implemented via a custom resolver to
enable the logging of any blocked entities.
