> The problem appears in version 2.3.14.3 and in revision 1493157. I
> attached a one-line patch that fixes it.
> In method "ValidateVisitor.getJspAttribute", the loop over
> "el.iterator()" should break immediately after "deferred" is set to
> "true". All the iterations after "deferred" is set to "true" do not
> perform any useful work, at best they just set "deferred" again to
> "true".
> Method "evaluateExtraParams" in class "ActionError" has a similar loop
> (over "actionMessages"), and this loop breaks immediately after
> "isEmptyList" is set to "false", just like in the proposed patch.
> Other methods (e.g., "DebuggingInterceptor.printContext",
> "FileUploadInterceptor.isNonEmpty", "CollectVisitor.checkSeen",
> "JspDocumentParser.processChars") also have similar loops with similar
> breaks, just like in the proposed patch.
