 Usage of static fields from java.lang classes as EL expressions in
JSPs doesn't work when requested more than once

                 Key: WFLY-11086
                 URL: https://issues.jboss.org/browse/WFLY-11086
             Project: WildFly
          Issue Type: Bug
          Components: Web (Undertow)
    Affects Versions: 14.0.0.Final
            Reporter: Adam Krajcik
            Assignee: Stuart Douglas
         Attachments: jsp-expression-lang.war

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