> In a jsp, if I use a tag such as {{{}<s:property value="(new 
> sample.ToBeInstanced('test')).getValue()" />{}}}, there is a silent failure 
> when the jsp is processed : the value of the tag is not printed out because 
> of silent NPE (the error is displayed in dev mode)
>  
> The error can be reproduced from this repository : 
> [https://github.com/FBibonne/basic-Struts-tag-error]
>  
> The first analyze indicates a bug inside the 
> {{org.apache.struts2.ognl.SecurityMemberAccess}} : it appears when an ognl 
> expression such as{{ (new com.mycompany.MyClass()).method()}}
> While processing security checks before the ognl runtime calls the 
> constructor, the program executes the method 
> _org.apache.struts2.ognl.SecurityMemberAccess#isAccessible_
> Inside this method, we pass through _the case where target is a class object_ 
> . At the end of this block, the {{target}} becomes null (line 153). So the 
> next test  
> ({_}org.apache.struts2.ognl.SecurityMemberAccess#checkProxyObjectAccess{_}, 
> line 160) is executed with target as null. But as {{checkProxyObjectAccess}}  
> calls  {{ProxyUtil.isProxy(target)}} with target as null, it raises a 
> NullPointerException.
>  
> Here is the error message in the log in devMode :
> {noformat}
