>             Project: Struts 2
>          Issue Type: Improvement
>          Components: Core
>    Affects Versions: 7.0.3
>            Reporter: Markus Fischer
>            Assignee: Lukasz Lenart
>            Priority: Trivial
>             Fix For: 7.2.0

>  Remaining Estimate: 0h
>
> In Java 25 the use of the three-letter time zone IDs is discouraged, probably 
> since Java 8. Java 25 now prints explicit warnings like:
>  
> {code:java}
> WARNING: Use of the three-letter time zone ID "ACT" is deprecated and it
> will be removed in a future release{code}
>  
> See also [https://bugs.java.com/bugdatabase/view_bug?bug_id=8342550]
> This may be due to the use of code like
>  
> {code:java}
> private static final TimeZone GMT = TimeZone.getTimeZone("GMT");{code}
>  
> We should use the full IANA IDs like "Europe/London".
