RESTEasy is using SLF4J 1.5.8 instead of a more recent 1.6.X release

There is a listed "breaking" change between SLF4J 1.5.X and 1.6.X.

See : : http://slf4j.org/news.html

The log method in LocationAwareLogger interface now admits an additional parameter of type Object[] representing additional arguments of the log request.
Due to this modification, slf4j-api version 1.6.x will not work with bindings shipping with SLF4J 1.5.x – bindings shipping with 1.6.x must be used.

To resolve this, we would like to move to a 1.6.x, however RESTEasy still depends on 1.5.8.
Can this dependency be upgraded?
