--------------------------------------
[~slfan1989] - I've noticed your conversation with [~bpatel] in HADOOP-15984
while I was looking for status of a Jett77y upgrade, so I created this ticket,
and I can start with working on this - if you think my approach is correct.
> Upgrade javax to jakarta
> ------------------------
>
> Key: HADOOP-19395
> URL: https://issues.apache.org/jira/browse/HADOOP-19395
> Project: Hadoop Common
> Issue Type: Improvement
> Components: common
> Affects Versions: 3.5.0
> Reporter: Yaniv Kunda
> Priority: Major
>
> The project uses old libraries in the {{javax.*}} package namespace, mainly
> {{javax.servlet}} & {{{}javax.annotation{}}}.
> For example, the old servlet-api is included via the following dependency
> management:
> {code:xml}
> <dependency>
> <groupId>jakarta.servlet</groupId>
> <artifactId>jakarta.servlet-api</artifactId>
> <version>4.0.4</version>
> </dependency>
> {code}
> Note that while the artifact is in maven's `jakarta.servlet` namespace, it
> includes the `javax.servlet` classes - versions 5 and above include the
> `jakarta.servlet` classes.
> The scope of its use is extensive, spanning most modules, and in many cases
> in public classes - however I'm not sure if any are considered a public API.
> One caveat is that the current Jetty version (9.4.x) doesn't work with the
> `jakarta.servlet` namespace, so it will still need to use the previous
> `javax.servlet` namespace, but the latter can be used by getting
> `javax.servlet:javax.servlet-api:4.0.1` specifically where it is used - and
> having the old namespace for the maven coordinates as well means it wouldn't
> cause a conflict.
> I believe that the first logical step is to upgrade to version 5.0.0, which
> is the first version that uses the `jakarta.*` package namespace, but is also
> the last that is Java 8 compatible, and upgrade again to 6.1.0 once hadoop
> migrates to Java 17 as a minimum A new Java 17 baseline will also support
> upgrading Jetty, which at the latest version 12 can work with all servlet-api
> versions.
