[jboss-jira] [JBoss JIRA] (WFLY-10718) Usage of static fields from java.lang classes as EL expressions in JSPs doesn't work for servlet 4.0

Thu Jul 19 07:23:00 EDT 2018

     [ https://issues.jboss.org/browse/WFLY-10718?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jan Stourac updated WFLY-10718:
-------------------------------
    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|https://github.com/wildfly/wildfly/blob/master/testsuite/integration/basic/src/test/java/org/wildfly/test/integration/jsp/JspELTestCase.java] but it does not cover Servlet 4.0.

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 and instead a blank string is rendered for them. 

More details in the linked forum thread https://developer.jboss.org/thread/271825
