-------------------------------
Summary: 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
Reporter: Brian Andle
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 https://issues.apache.org/jira/browse/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
