adoroszlai opened a new pull request, #6897:
URL: https://github.com/apache/ozone/pull/6897
## What changes were proposed in this pull request?
Building Ozone with Java 9+ (but still targeting Java 8 with
`javac.version=8`) and running with Java 8 results in:
```
NoSuchMethodError: java.nio.ByteBuffer.position(I)Ljava/nio/ByteBuffer;
at
org.apache.hadoop.ozone.common.ChunkBufferImplWithByteBuffer.duplicate(ChunkBufferImplWithByteBuffer.java:111)
```
It can be reproduced in Hadoop compatibility tests, because Hadoop images
still ship with Java 8, while Ozone images have newer Java.
CI tweak for repro:
https://github.com/adoroszlai/ozone/commit/33f7f4b2cc26e380ee7e570b990ef9962021b89c
Failure:
https://github.com/adoroszlai/ozone/actions/runs/9792172547/job/27038142506#step:6:9
Exception can be seen in `log.html` in the [test
artifact](https://github.com/adoroszlai/ozone/actions/runs/9792172547/artifacts/1667509237).
Blog with great explanation of the problem and solution:
https://www.morling.dev/blog/bytebuffer-and-the-dreaded-nosuchmethoderror/
It can be fixed by setting `--release` for `javac`, via
`maven.compiler.release`. This is a new option for JDK 9+, so it must be done
conditionally, in a profile.
