I can build gerrit with JDK 16 from this change: [1]: And can confirm, that major byte code version is 60, as expected: [1] https://gerrit-review.googlesource.com/c/gerrit/+/301362 |
|
Could you please upload JDK 16 archives to Bazel mirror? |

There was a problem hiding this comment.
Would you mind also adding "16" to the JAVA_VERSIONS in src/test/shell/BUILD? Those tests have much better coverage and will make sure JDK16 works.
nit: there are some "14" left in the tests and those test fail because JDK14 was removed. If you also care replacing them with "15" or removing them.

Thanks for the review.
After adding the "16" to the And this diff fixed it: diff --git a/tools/jdk/default_java_toolchain.bzl b/tools/jdk/default_java_toolchain.bzl

This test is failing: //src/test/shell/bazel:bazel_coverage_java_jdk16_toolchain_released_test FAILED in 104.9s I can reproduce it locally but it's hard to see what is the root cause?! |
|
I think I see what's going on. I extracted a reproducer repository for coverage based on the test: https://github.com/davido/bazel_coverage_src_and_test_same_package And all I changed is added these lines to cat .bazelrc Now, running coverage with new IOW, currently used jacoco distribution on Bazel@HEAD doesn't support Java 16 yet. Bazel is still using JaCoCo 0.8.3: cat third_party/java/jacoco/BUILD While the experimental support for Java 16 was added in release 0.8.6: [1] in this PR: [2]. [1] https://github.com/jacoco/jacoco/releases/tag/v0.8.6 |
Thanks for the pointer, I see, that should just pass?! |

Thanks for bumping If it works, could you merge it and release yet another |
No need. None of the files in this PR are a part of java_tools. I reorganised this a while ago to make things easier. We merge this PR and you're done. |
Great news. How can I activate the new toolchain built from this PR in bazel? I'm asking because coverage Java 16 tests are still failing. Even though, I've rebased this PR on Bazel@HEAD. |
|
I can reproduce the failure locally, and see this if I try to run coverage with Java 16 toochain: |
|
If I disable the sandbox, it doesn't find Jacoco either: Looking into the directory structure, it's here: |
Just using --{,tool_}java_language_version=16, --{,tool_}java_runtime_version=16 flags. I can reproduce the same problems locally. They are weird though: Possibly connected to some new visibility/exports requirement in JDK16? Would you mind disabling coverage test on JDK16, opening a separate issue for it and pushing this PR forward? |
Sure, will update PR in a moment and open coverage issue for JDK 16. Thanks! |
