JIRA: HADOOP-19725. [JDK17] Upgrade SpotBugs Version to Support JDK 17 Compilation.

The error in sputbug is currently caused by incompatibility with JDK 17.

How was this patch tested?

CI.

For code changes:

Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?

…ilation.

@cnauroth @szetszwo After upgrading to JDK 17, I found that spotbug could not run properly because the current version does not support JDK 17. To resolve this issue, I upgraded the versions of the two related plugins. The changes have been tested locally, and the results are as expected.

I have completed the investigation of the mvnsite build issues and confirmed that the problem is related to the JDIFF module. We plan to submit a separate PR to fix and optimize this issue.

    <dependency-check-maven.version>7.1.1</dependency-check-maven.version>
-    <spotbugs.version>4.2.2</spotbugs.version>
-    <spotbugs-maven-plugin.version>4.2.0</spotbugs-maven-plugin.version>
+    <spotbugs.version>4.8.3</spotbugs.version>


Why not 4.9.7 (or 4.8.6)?

https://mvnrepository.com/artifact/com.github.spotbugs/spotbugs

Thank you for reviewing! You made a very good point — I’ll update this PR accordingly.

spotbugs 4.9 onwards requires JDK 11+, are we ready to drop Java 8 support on trunk?

currently, trunk GitHub Actions site jobs fail due to this upgrade.

@szetszwo @slfan1989

~~@slfan1989 , we probably should move back to 4.8.x?~~

@pan3793 , Actually, SpotBugs is build tool but not a runtime library. One option is to run SpotBugs code analysis using jdk11 or above. The runtime still can be built with and run with JDK8. Would it work?

Thank you all for the discussion! I believe what @szetszwo mentioned makes sense.

Let me explain the situation:

We have upgraded the JDK version in the trunk to JDK 17 and JDK 21. Regarding the issue of mvn site failing to compile, this is a known issue and is unrelated to the SpotBugs plugin.

Here’s a detailed explanation of the two issues:

The reason for upgrading is that SpotBugs 4.2.0, as indicated by Yetus, does not support scanning for JDK 17 and above. Therefore, we upgraded to a higher version, choosing SpotBugs 4.9.7. From my perspective, upgrading to SpotBugs 4.9.7 is reasonable. Although new warning messages have appeared, I do not plan to roll back the version. Issue after upgrading to SpotBugs 4.9.7: Due to the introduction of new rules, new warning messages appeared during compilation. We have formulated a solution:

Temporary solution: We are filtering out these new warnings globally to mitigate the impact of the new filtering rules. You can refer to the related PR HADOOP-19731. Fix SpotBugs warnings introduced after SpotBugs version upgrade. #8053.

mvn site compilation failure: This issue is related to our custom annotations, which we can see in the error logs. We already have a solution for this:

Referring to PR HADOOP-19402. [JDK11] JDiff Support JDK11. #8038. we have rewritten all the annotations under hadoop-common-project/hadoop-annotations/src/main/java17/org/apache/hadoop/classification/tools/* and added support for JDIFF under JDK 17.

Currently, these two PRs are being followed up by HuaLong. In offline communication, HuaLong mentioned that he is currently on leave, so it may take some more time to complete.

I hope this makes the situation clearer!

szetszwo · 2025-10-15T15:23:00Z

-    <spotbugs.version>4.2.2</spotbugs.version>
-    <spotbugs-maven-plugin.version>4.2.0</spotbugs-maven-plugin.version>
+    <spotbugs.version>4.8.3</spotbugs.version>
+    <spotbugs-maven-plugin.version>4.7.3.6</spotbugs-maven-plugin.version>


Similarly, why not 4.9.7.0 (or 4.8.6.7)?

Thanks @slfan1989 . LGTM. +1. I think it is smooth after check spotbug release changes and other apache projects upgrade feedbacks. TBH, I am not check it with new JDK version carefully.
