[DISCUSS] Support for Java 11 & 17
Hi All,
Currently, we compile and verify Ozone only with Java 8. As far as I know,
we haven't tested Ozone either with Java 11 or 17.
We should start compiling and testing Ozone with higher versions of Java to
make the version upgrade easier in the future.
This will enable us to upgrade the Java version whenever required and
deprecate older version(s) of Java if needed.
The plan here is to add support to choose the Java version (8, 11 & 17) to
compile Ozone.
With this, we will have the option to compile and run Ozone with
- Java 8
- Java 11
- Java 17
We can also add pre-commit checks to make sure that all the changes made to
Ozone work on all the supported Java versions.
Note: We will not be able to use new features of Java until we
deprecate and remove the older version(s).

Thanks,

Hi Nanda,
On using Java 11 ozone builds - It should be noted that when running our
dev-support findbugs script on the build I found it generates many findings
(NULL related) that are not reported when run on Java 8 compiled build.
Generally, I look for a clean findbugs pass on a Java 8 build to avoid the
findbugs findings I find on a Java 11 build.

Thanks for taking a look at this Attila.
Even though we use Java 11 for compilation, the binaries are generated for
Java 8.
This is because we have mentioned it in the pom file
*<javac.version>1.8</javac.version>*
In this scenario, JDK 11 compiles Ozone code and generates binary
targeting Java 8.
If we update the Java version to 11 in pom file, Ozone compilation actually
fails. (HDDS-7633 <https://issues.apache.org/jira/browse/HDDS-7633>)
Instead of just compiling it with JDK 11 (current method), we can introduce
different maven profiles to add support for compiling Ozone using different
Java versions.

CI compiles each commit with both Java 8:
https://github.com/apache/ozone/blob/d6f63bf2e53ac8a4220ee829d8bbb2427dd7d3fa/.github/workflows/ci.yml#L60-L68
https://github.com/apache/ozone/actions/runs/3685851489/jobs/6237313319#step:6:12
and Java 11:
https://github.com/apache/ozone/blob/d6f63bf2e53ac8a4220ee829d8bbb2427dd7d3fa/.github/workflows/ci.yml#L117-L126
https://github.com/apache/ozone/actions/runs/3685851489/jobs/6237545246#step:6:12
Acceptance tests run Ozone with Java 11, but using the binaries
compiled with Java 8:
