[xwiki-devs] [Proposal] Stop logging errors when a wiki macro cannot be registered due to insufficient privileges for the asked visibility

Hi friends, I'm proposing a patch (see http://jira.xwiki.org/jira/browse/XWIKI-5439) to stop logging a full exception at error level when the wiki fails to register a wiki macro due to insufficient privileges for the asked visibility. This is currently what happens, and it can trash your log, for example if you initialize a farm with hundreds of wikis throwing couple of times such error :) Thing is this is not a real error, in the sense "something went wrong" so it should be logged at the debug level. The patch introduce a new exception : org.xwiki.rendering.macro.wikibridge.InsufficientPrivilegesException, which when caught by the wiki macro initializer is logged at debug level, by opposition of the more generic org.xwiki.rendering.macro.wikibridge.WikiMacroException that remains logged at error level. I'm calling for a vote since the patch introduce a API signature change. Though I tend to think it's internal enough not to go through deprecation cycle. My +1 Jerome.
