> This issue is regarding a support case [1] where JBoss throws the below given error while evaluating ternary operators in Expression Language(EL) written in JSP. I found this issue there in EAP 5.1.1 (JBoss Web 2.1.3.GA) as well but interestingly this issue does not occur in EAP 4.3.x (JBoss Web 2.0.0 GA CP05).
> I have attached a sample test case, which once you deploy and hit the application like this (http://localhost:8080/TestWS) it throws the following ERROR.
> 2011-07-27 12:34:51,197 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/TestWS].[jsp]] (http-127.0.0.1-8080-1) Servlet.service() for servlet jsp threw exception

> As per the bug opened for the same issue faced in Apache Tomcat, as mentioned in the following URL [2], the issue has been fixed and the fix has been included in Apache Tomcat version 6.0.23 onwards.
> There exists a JIRA [3] where for similar issue we are rebasing to Version 6.0.21 , hence I am opening this fresh JIRA so that a patch could be provided for the existing users of EAP 5.x and also this change could be included into EAP 5.1.2 as well.
