[Remy Maucherat (JIRA)]

    [ https://issues.jboss.org/browse/JBWEB-290?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12949260#comment-12949260 ] 

Remy Maucherat commented on JBWEB-290:
--------------------------------------

This is not going to get fixed or looked at as this is scriplet = a Java code fragment. It is equivalent to writing the same Java code in a Servlet.

> 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?
