Markus Fischer created WW-5576:
----------------------------------
Summary: In Java 25: the use of the three-letter time zone IDs is
deprecated
Key: WW-5576
URL: https://issues.apache.org/jira/browse/WW-5576
Project: Struts 2
Issue Type: Improvement
Components: Core
Affects Versions: 7.0.3
Reporter: Markus Fischer
Fix For: 7.2.0
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}

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".
