[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-1974) NPE in Tomcat parseParameters()

NPE in Tomcat parseParameters() ------------------------------- Key: JBSEAM-1974 URL: http://jira.jboss.com/jira/browse/JBSEAM-1974 Project: JBoss Seam Issue Type: Bug Components: Wiki Reporter: Christian Bauer Assigned To: Christian Bauer Priority: Minor This is still a mystery, only occurs from time to time on the production site. Google says that this might be related to the 64 bit VM, others say that the lifecycle of the request object usage is wrong. The crazy part is that the Authenticator component doesn't even have any @RequestParameter anymore, so no idea why Seam wants to inject it.
