             Summary: Optimize string literals inside jsp expressions 
                 Key: JBWEB-290
                 URL: https://issues.jboss.org/browse/JBWEB-290
             Project: JBoss Web
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: Tomcat
    Affects Versions: JBossWeb-3.0.0.Final
            Reporter: John O'Hara
            Assignee: Remy Maucherat


After setting genStringAsCharArray=true, we continue to see StringBuilder concatenating string literals for each jsp request for some of our jsp pages; instead of creating a static char[].

This occurs when a string literal is included in a jsp expression, e.g.;

<%="<INPUT type=\"hidden\" name=\"name\" value=\"" + obj.getName() + "\">"%>

Is it possible to identify string literals inside expressions during the tokenization phase of parsing jsp pages in apache jasper and treat them as text nodes so that the apache jasper generator can apply the same optimizations as string literals outside the jsp expression?
