Subject [Bug 54792] New: IllegalStateException with chat sample
Date Tue, 02 Apr 2013 20:54:28 GMT
https://issues.apache.org/bugzilla/show_bug.cgi?id=54792

            Bug ID: 54792
           Summary: IllegalStateException with chat sample
           Product: Tomcat 8
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
          Assignee: dev@tomcat.apache.org
          Reporter: rstoyanchev@yahoo.com
    Classification: Unclassified

This looks related to 54659 and 54724 but possibly a new issue. To reproduce,
open the chat sample page, send a message or two, and then close the browser
tab. The following exception appears in the log and it doesn't seem to step
from anything done in the application:
