I started a thread at https://markmail.org/message/n76cchtriexxmgm7, excerpt:
- Why having the ftl handlers only in webtools controller? BTW it makes the XSD documentation awkward because it speaks about the ftl handlers being in handlers-controller.xml
- Why not using error.ftl in common-controller.xml instead of error.jsp?
- Same question for plugins.
I believe we could change all that and definitely get rid of error.jsp (error.ftl is already in all supported releases branches)
