What causes NullPointerException after removing ROOT.war in JBoss EAP ?
Issue
After deleting server/default/deploy/jboss-web.deployer/ROOT.war for security reasons, the following issue occurred when browsing to a non-existent path (e.g. http://localhost:8080/XXX):
ERROR [CoyoteAdapter] An exception or error occurred in the container during the request processing
java.lang.NullPointerException
at org.apache.catalina.connector.CoyoteAdapter.parseSessionCookiesId(CoyoteAdapter.java:507)

The server acts as if the page exists, though it is blank.
