Ganesh Jung commented on MYFACES-2543:
--------------------------------------
Now that the spec issue is solved here's my suggestion to treat this issue:
MyFaces shouldn't make any distinction between
http://java.sun.com/dtd/facelet-taglib_1_0.dtd taglibs and
http://java.sun.com/xml/ns/javaee/web-facelettaglibrary_2_0.xsd taglibs.
Trying to craft an algorithm that distinguishes between "good taglibs" and "bad
taglibs" will unerringly fail in some cornercases. A jar may contain some
com.sun.facelets classes or some java taghandlers, but the defined tags never
use them. Or maybe the developer knows how to call the tags so that the legacy
code doesn't run.
Nobody will blame MyFaces for ClassNotFoundExceptions when stumbling onto a
com.sun.facelets reference, but MyFaces will be blamed if fully functional
taglibs don't run because of some heuristic jar scanning that MyFaces does at
startup.
