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.
