What’s the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.
Haven’t minimized this yet, also not yet tested with newer bazel releases
Which operating system are you running Bazel on?
NixOS
What is the output of bazel info release?
release 5.1.1- (@non-git)
If bazel info release returns development version or (@non-git), tell us how you built Bazel.
NixOS nixpkgs
What’s the output of git remote get-url origin; git rev-parse master; git rev-parse HEAD ?
No response
Have you found anything relevant by searching the web?
No response
Any other information, logs, or outputs that you want to share?
https://openjdk.org/jeps/403 since java16 default is
-illegal-access=deny disables all illegal-access operations except for those enabled by other command-line options, e.g., --add-opens.
Something like --add-opens=java.base/java.lang=ALL-UNNAMED for server jvm flags could be a workaround
somewhat related https://github.com/bazelbuild/bazel/issues/5599
reflection is still present in latest bazel source code https://github.com/bazelbuild/bazel/blob/master/src/main/java/com/google/devtools/build/lib/unsafe/StringUnsafe.java

The same issue happens for me with Bazel 5.3 and OpenJDK 17,
StringUnsafe’s constructor fails with anjava.lang.reflect.InaccessibleObjectException: Unable to make java.lang.String(byte[],byte) accessible: module java.base does not "opens java.lang" to unnamed moduleerror:This is https://openjdk.org/jeps/403
The workaround is to pass
--add-opens=java.base/java.nio=ALL-UNNAMEDas a server JVM flag. The bazel launcher already passes that flag, but only for embedded JDKs:https://github.com/bazelbuild/bazel/blob/03ad0cd1203b7b54ec02ea3f5788d1d673a9d6d6/src/main/cpp/blaze.cc#L362-L367
