Re: [undertow-dev] Deadlock in JSP page on Wilflfy 8.0 Alpha 4 with umlauts

From: "Wolfgang Knauf" <wolfgang.knauf(a)gmx.de&gt; To: undertow-dev(a)lists.jboss.org Sent: Wednesday, 28 August, 2013 10:28:24 PM Subject: [undertow-dev] Deadlock in JSP page on Wilflfy 8.0 Alpha 4 with umlauts Hi all, hope this is the right place and the correct component to post a possible Undertow bug: I have a simple EAR application, used to test the JavaEE feature of a one-to-many-relationship. It contains an EJB jar and a WAR file, bundled in an EAR file. Whenever I add an umlaut in an input field and submit the form, WildFly hangs up while processing the request to display the result page (which should display a list of my entities). As this happens when generating the JSP page, I assume an Undertow issue. To reproduce: 1) deploy "KuchenZutat.ear" to WildFly (it uses the "java:jboss/datasources/ExampleDS", so no configuration changes needed). 2) browse to "http://localhost:8080/KuchenZutatWeb/" 3) Klick "Neu" 4) enter something with an umlaut, e.g. "Käsekuchen" 5) click OK Now the server hangs. It works when avoiding umlauts. Here are two stack traces, which I took by debugging the server with Eclipse and breaking into debugger at random times. Note that the thread name is different in the two stack traces - I took them at different server runs. "CoderResult.unmappableForLength()" seems to be the place for the endless loop.
