Hello,
Our team publishes Microsoft's build of OpenJDK, and we have observed some test
failures after upgrading our macOS agents from 10.15 to MacOS 11. We have also
seen these failures on macOS 12.x. The tests that are encountering issues are
in compiler/aot category. We are only observing these issues in our JDK11u
builds. The exact command line I used to reproduce the error locally is:
/Users/JEG/jdk-11.0.18+10/Contents/Home/bin/java -Xmx512m -jar
/Users/JEG/jtreg/lib/jtreg.jar -agentvm -ignore:quiet -automatic -xml
-vmoption:-Xmx512m -timeoutFactor:4 -concurrency:1
-testjdk:/Users/JEG/jdk-11.0.18+10/Contents/Home -nativepath:/
Users/JEG/jdk-11.0.18+10-test-image/hotspot/jtreg/native
-verbose:fail,error,summary -exclude:test/hotspot/jtreg/ProblemList.txt
test/hotspot/jtreg/compiler/aot/TestHeapBase.java
Which resulted in the following exception:
Exception in thread "main" java.lang.InternalError: ld: dynamic main
executables must link with libSystem.dylib for architecture x86_64

The version of macOS which I reproduced this error was:
openjdk-jdk11u % sw_vers
ProductName: macOS
ProductVersion: 11.4
BuildVersion: 20F71
Initial triage on our end suggests that the linker for these tests is invoked
in Linker.java, where we may require additional arguments passed into the "ld"
command. Specifically, including the library path. The change that may have
introduced this behavior is documented here:
https://developer.apple.com/documentation/macos-release-notes/macos-big-sur-11_0_1-release-notes.
The important bit, I think, is:
* New in macOS Big Sur 11.0.1, the system ships with a built-in dynamic
linker cache of all system-provided libraries. As part of this change, copies
of dynamic libraries are no longer present on the filesystem. Code that
attempts to check for dynamic library presence by looking for a file at a path
or enumerating a directory will fail. Instead, check for library presence by
attempting to dlopen() the path, which will correctly check for the library in
the cache. (62986286)
Has anyone encountered this issue before or would be willing to provide insight
to what the root cause may be?
Thanks!
