> Eliminting explicit diamone operation is only available in JDK 7 or higher. 
> But, the default compiler source VM version is 1.5 in jetty. It causes 
> compilation error in web UI. So, we need to set the following parameters to 
> web.xml in each web app:
> {noformat}
> <servlet id="jsp">
>     <servlet-name>jsp</servlet-name>
>     <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
>     <init-param>
>       <param-name>compilerSourceVM</param-name>
>       <param-value>1.8</param-value>
>     </init-param>
>     <init-param>
>       <param-name>compilerTargetVM</param-name>
>       <param-value>1.8</param-value>
>     </init-param>
>   </servlet>
> {noformat}
