> Project: Struts 2
> Issue Type: Bug
> Components: Plugin - Embedded JSP
> Affects Versions: 2.3.14.3
> Environment: any
> Reporter: Adrian Nistor

>
> The problem appears in version 2.3.14.3 and in revision 1495522. I
> attached a two-line patch that fixes it. This problem and the
> attached patch are similar to the previously fixed WW-4115 and its
> patch.
> In method "ValidateVisitor.isExpression", the loop over "nodes" should
> break immediately after "elExpression" is set to "true". All the
> iterations after "elExpression" is set to "true" do not perform any
> useful work, at best they just set "elExpression" again to "true".
