      Java EE7 (which supports EL 3.0 spec) allows JSPs to use EL expressions like:

      <html>
   <body>
      foo: --- ${Boolean.TRUE} ---<br>
      bar: --- ${Integer.MAX_VALUE} ---<br>
   </body>
</html>

      However, the

      ${Boolean.TRUE}

      and

      ${Integer.MAX_VALUE}

      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) doesn't cover the situation when request is sent more than once.
