[bazel.build] Problem with /install/compile-source

Page link:

https://bazel.build/install/compile-source

Problem description (include actual vs expected text, if applicable):

I am running ubuntu-20.04 inside an arm64 virtual machine.
I am trying to build bazel from scratch.
I followed the instructions in the section "Build Bazel from scratch (bootstrapping)", but the command env EXTRA_BAZEL_ARGS="--tool_java_runtime_version=local_jdk" bash ./compile.sh gave an error:

Unable to make java.lang.String(byte[],byte) accessible

It turns out that I should not use openjdk-21 in my environment. openjdk-11 works fine for me.

I suggest you change the following text

JDK. Version 21 is required.

to

JDK. Version 11 is required.

Where do you see this issue? (include link to specific section of the page, if applicable)

Any other information you'd like to share?

@ccw-li Which version of Bazel are you trying to bootstrap?

@hvadehra I'm a bit surprised that Bazel doesn't bootstrap with JDK 21, do you know anything about this?

[hvadehra]

I can't think of any reason it wouldn't. I think an answer to your first question would help.

[ccw-li]

I am bootstrapping bazel-6.5.0.

[hvadehra]

I am bootstrapping bazel-6.5.0.

Thanks, I'll see if I can repro.

fwiw, if you look at the docs for 6.5.0 here https://bazel.build/versions/6.5.0/install/compile-source#bootstrap-bazel , it does say jdk 11. The change to 21 became necessary only recently (the default docs are for Bazel@HEAD).

Thanks a lot. I didn't know there is a separate manual for each version.
