JBoss EAP 6.1.1 servlet Response recycling issue

We are encountering some technical problems about jbossweb. After did some googling, we found what someone discussed in thread http://markmail.org/message/oljd4ywmiltqfm2h#query:+page:1+mid:mrkksetlomtxg5ml+state:results is exactly what we encountered.
However, I can not link to the JIRA ticket listed https://issues.jboss.org/i#browse/WFLY-3328 , can you provide me some advice on how to access the ticket, or provide some patch/fix/howto about this issue?
