Brian Andle commented on WW-5403:
---------------------------------
[~lukaszlenart] , I believe we're good. We have a nightly set of jars in code,
not prod, and we haven't seen any automation issues directly related to the
upgrade. We do have some manual testing to do for areas not automated but for
the sake of this ticket, the changes in
[https://github.com/apache/struts/pull/898] and
[https://github.com/apache/struts/pull/900] incapsulate everything need for at
least our migration.
> Struts 2.5 to 6.x migration issues caused by removal of deprecated code
> within a minor release
> -----------------------------------------------------------------------------------------------
>
> Key: WW-5403
> URL: https://issues.apache.org/jira/browse/WW-5403
> Project: Struts 2
> Issue Type: Bug
> Components: Core
> Reporter: Brian Andle
> Priority: Major
> Fix For: 6.4.0
>
>
> Created this Jira to represent the additional discussion in WW-5251 because
> there appears to be some breaking changes that could prevent Struts users
> from being able to successfully migrate to 6.x. Since these are the result of
> other tickets the discussion should be moved to a new Jira.
> Text from my comments in WW-5251 which results in breaking changes, removal
> of deprecated methods, in a minor version update of the major version that
> introduced the deprecations.
> This poses a possible risk to consumers of Struts who may need to attempt an
> upgrade to 6.x when 2.5 goes out of support in early 2024.
>
> --------
> I've started building our application locally and now hitting various compile
> issues, in our code, from WW-5304 (and others) . Specifically, at the moment,
> {{core/src/main/java/com/opensymphony/xwork2/ActionContext.java}} dropped
> {{getName()}} which wasn't marked as deprecated. Looks like
> `org.apache.struts2.interceptor.NoParameters` was also removed. I'm still
> working though building our app, one fail at a time.
> Should these deprecations been dropped in minor releases as many were
> initially marked as deprecated in 6.0.0 with WW-4789 WW-3788 (and any others
> as I find them)?
> I was able to get our app built, and started and light smoke test, and still
> maintain compatibility with our sister project (might not be the case with
> every Struts consumer though). Had to make the following additional
> adjustments to get from 6.1.2.2 to ~6.4.0.0 WW-5251 revert branch:
> * {{ActionContext.getContext().getName()}} _*->*_
> {{ActionContext.getContext().getActionName()}}
> * {{org.apache.struts2.interceptor.NoParameters}} _*->*_
> {{org.apache.struts2.action.NoParameters}}
> ** The {{action}} version does not exist in 6.1.2.2
> *
> {{actionInvocation.getInvocationContext().setParameters(HttpParameters.create(parameters).build())}}
> _*->*_
> {{actionInvocation.getInvocationContext().withParameters(HttpParameters.create(parameters).build())}}
> * Caffeine jar is now a required dependency
