> Java EE7 (which supports EL 3.0 spec) allows JSPs to use EL expressions like:
> {code}
> <html>
>    <body>
>       foo: --- ${Boolean.TRUE} ---<br>
>       bar: --- ${Integer.MAX_VALUE} ---<br>
>    </body>
> </html>
> {code}
> However, the
> {code}
> ${Boolean.TRUE}
> {code}
> and
> {code}
> ${Integer.MAX_VALUE}
> {code}
> in the above example aren't evaluated correctly if request is send more than once, and instead a blank string is rendered for them. The [^jsp-expression-lang.war] used in Steps to reproduce works correctly in 7.2.0.CD13.
> More details in the linked forum thread https://developer.jboss.org/thread/271825.
> The existing tests([JspELTestCase|https://github.com/wildfly/wildfly/blob/master/testsuite/integration/basic/src/test/java/org/wildfly/test/integration/jsp/JspELTestCase.java]) doesn't cover the situation when request is sent more than once.
