servlet container has no UTF-8 encoding default set, produces garbage on form submissions ----------------------------------------------------------------------------------------- Key: WFLY-9337 URL: https://issues.jboss.org/browse/WFLY-9337 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 11.0.0.CR1 Reporter: Mr Gruust Assignee: Stuart Douglas The problem described over there https://stackoverflow.com/questions/31205287/encoding-servlets-with-utf-8... still exists with the latest release. I had to explicitly set UTF-8 as default encoding to make resteasy properly decode form submissions and not decode UTF-8 as latin-1 (at least it looks a lot like that to me). On top of that, persisting session ids to file store (without using <distributable/> in web.xml) tends to lose the session store when reloading the (unmanaged) webapp too fast during development.
