From: "Wolfgang Knauf" <wolfgang.knauf(a)gmx.de&gt; Cc: undertow-dev(a)lists.jboss.org Sent: Thursday, 29 August, 2013 10:04:37 PM Subject: Re: [undertow-dev] Deadlock in JSP page on Wilflfy 8.0 Alpha 4 with umlauts Many thanks! I am a bit ashamed, because in my sample, I forgot everything that I know about encodings in JSP pages, and relied on the server defaults for years... This deadlock bug was the appropriate punishment for this laziness ;-). After declaring everything properly ("@page contentType=...", <meta http-equiv="content-type" ...>) and applying "request.setCharacterEncoding(...)", it works like a charm.
