Attach files problem on Glassfish 3.1.2

After upgrading Glassfish to last version 3.1.2 functionality of files attaching stops working. No errors & logs. No any changes in configs & xwiki params, no any upgrade of any part of xwiki - only upgraded Glassfish. I can select attach, when I press button "attach" - forwarded to .../MyPage?viewer=attachments instead of .../MyPage#Attachments and NO ATTACH. Functionality of downloading files works without problems. More details described here: http://xwiki.475771.n2.nabble.com/Need-help-Attachments-doesn-t-work-td7392072.html
Also, exists same problem on fresh install of XWiki (when used glassfish 3.1.2 as a application server) - user cannot attach default xwiki.xar. More details described here http://xwiki.475771.n2.nabble.com/xwiki-3-5-default-xar-import-td7365205.html
This affected xwiki versions 3.4 & 3.5 and only with glassfish 3.1.2.
