This test recently passed in a different run of the same tier8 task. It was skipped in this run, as it should always be when running on hardened OSX system: ----------System.out:(12/608)---------- STDOUT: Executable=/System/Volumes/Data/mesos/work_dir/jib-master/install/jdk-22+4-215/macosx-x64-open.jdk/jdk-22.jdk/Contents/Home/bin/java STDOUT: Identifier=net.java.openjdk-ea.java STDOUT: Format=Mach-O thin (x86_64) STDOUT: CodeDirectory v=20500 size=644 flags=0x10000(runtime) hashes=9+7 location=embedded Target JDK is hardened.

Note that isHardenedOSX() does not check the codesign process exit code. It just spawns the process and tries to read the output. Possibly codesign simply failed to run for some reason.
