Howard M. Lewis Ship commented on TAP5-1729:
--------------------------------------------
Doing some research:
http://www.julienlecomte.net/blog/2008/10/80/
Apparently, YUICompressor introduces some hacks to Rhino, and does some
classloading tricks to make it work ... likely that is the problem, as Tomcat's
classloaders are complicated and are well known to cause other problems
(Tapestry has a number of hacks and patches to deal with Tomcat's class
loaders).
