>             Project: Struts 2
>          Issue Type: Bug
>          Components: Value Stack
>    Affects Versions: 2.3.15.1, 2.3.15.3, 2.3.16
>         Environment: Mac OSX - JDK 1.7_0_25 and 45
>            Reporter: Andrew Carr
>   Original Estimate: 12h
>  Remaining Estimate: 12h

>  The key thing to remember is this problem does
> not occur using Struts 2.3.4.1.  There are a couple of false
> indicators that I have worked through and I do believe this is due to
> a recent change in the code.  I have debugged it thoroughly and would
> appreciate any pointers in the right direction.
> I have tested this on MAC/OSX with Java 7u25 and 7u45, and tomcat
> 7047, 800rc5, 800rc9 as well.
> Call to TextParseUtil.translateVariable throws Null Pointer exception.
> This happens when I call
> TextProviderFactory.createInstance(Class,LocaleProvider).getText(String)
> from an "init()" method of an interceptor.
> This works fine in struts 2.3.4.1.  After upgrading to 2.3.15.1,
> 2.3.15.3 and 2.3.16, the server fails to deploy the application with
> the following exception:
> {noformat}
> Caused by: java.lang.NullPointerException

> {noformat}
> The full stack trace is available here:
> http://pastebin.com/Us7AFxWT
> I have debugged the code update.  It appears this is happening when
> calling  ValueStack#findValue(java.lang.String) from the interceptor.
> I have time to work on a patch, if this issue is valid.
