[11.0.x] Calling HttpServletRequest.logout() with single sign-on enabled only works every second time ----------------------------------------------------------------------------------------------------- Key: WFLY-7019 URL: https://issues.jboss.org/browse/WFLY-7019 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 11.0.0.Alpha1 Reporter: Richard Janík Assignee: Stuart Douglas This issue has resurfaced with 11.0.0.Alpha1-SNAPSHOT. It has been previously reported and fixed in 10.1.0.Final. See "Steps to Reproduce". Logging out from an application only works every second time, e.g. HttpRequestServlet.logout() has to be called twice in order to have any effect. This doesn't occur without <single-sign-on/> enabled - logout() has the expected effect. I'm adding our security team members as watchers. I'm trying to create a test in the WildFly integration testsuite, but I'm currently failing ([1]). The test I have written is currently passing. I don't know why yet, but either the test is bad or there might be something specific about the issue. The reproducer from JBEAP-1282 still works (in other words, it is failing now that the issue has appeared again).
