WildFly core 3.0.0.Alpha16, which is used for 7.1.0.DR10 brought in Undertow 1.4.8, which seems to cause TCK regressions in the jsp tests (encoding, includes, secform) and the servlet tests (webservletdd, secform).

The root cause of a lot of these seems to be this error message:

http://pastebin.test.redhat.com/440680 shows the
"java.lang.IllegalArgumentException: UT010007: Two servlets specified
with same mapping *.jsp" failure.
http://wildflycts.mw.lab.eng.bos.redhat.com/tck_work/servlet/logs/server.log
is the entire server.log, which shows this error. I restarted this
test so we can see if it fails again.

It did fail again.

Looking at the diff from 1.4.6 (which was used in core 3.0.0.alpha15 which passed these tests) https://github.com/undertow-io/undertow/compare/1.4.6.Final...1.4.8.Final
This error message seems to have been introduced in 1.4.7 by https://github.com/undertow-io/undertow/commit/2cdaadc6352d75fc408ab52d063df4d079af19de

This commit might not be the cause of all the failures, but since we need to roll back to 1.4.6 anyway, more investigation can be done offline.

In order to avoid doing another core release we are overriding the undertow version in the full distribution. This should be reverted later, which is the purpose of this Jira.
