Usage of static fields from java.lang classes as EL expressions in JSPs doesn't work for servlet 4.0

    XMLWordPrintable

Details

    Description

      This seems to be back but this time with Servlet 4.0 only as 3.1 seems to work just fine. Current test is already in Wildfly testsuite but it does not cover Servlet 4.0.

      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 and instead a blank string is rendered for them.

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.
