Critical Description
I was testing proposed workaround to JSP include issue in WildFly 8.1 (https://issues.jboss.org/browse/WFLY-3385)
I replaced undertow-core, undertow-servlet and undertow-websockets-jsr in wildfly 8.1 modules with 1.1.0.Beta7 snasphot I built myslef but I got an IndexOutOfBoundsException in ServletPrintWriter.
So I replaced by official 1.1.0.Beta6 jar files and still got the same issue: http://pastebin.com/GunGKqqu
I even tried to update jastow to 1.0.1.Final but it did not make any difference with Undertow 1.1.0.Beta6
So I grabbed latest WildFly 9 build (#1334) from https://ci.jboss.org/hudson/view/All/job/WildFly-latest-master/
It included Undertow 1.1.0.Beta5, I copied the jars to wildfly 8.1 modules and this time it worked for me.
