Context: #9651

Recent versions of macOS, Safari, and tar(1) 1 interact such that if you manually download a tarball and extract it, all the extracted files contain the com.apple.quarantine extended attribute. This is a security feature, but it also means that the provisioned JDK cannot be used:

% $HOME/android-toolchain/jdk-21/bin/javac
zsh: operation not permitted: ./jdk-21/bin/javac

Which in turn means if you do something "reasonable" like download Microsoft OpenJDK and place it into $HOME/android-archives -- so that xaprepare doesn't need to download it again -- then the provisioned JDK will be unusable. Which makes @jonpryor sad.

Update Step_InstallAdoptOpenJDK.MacOS.cs to run
xattr -d -r com.apple.quarantine $HOME/android-toolchain/jdk-21. This will delete the offending extended attribute, allowing e.g. javac to run without error.

Recent versions of macOS, Safari, and **tar**(1) [^0] interact such
that if you manually download a tarball and extract it,
*all the extracted files* contain the `com.apple.quarantine`
extended attribute.  This is a security feature, but it also means
that the provisioned JDK *cannot be used*:

	% $HOME/android-toolchain/jdk-21/bin/javac
	zsh: operation not permitted: ./jdk-21/bin/javac

Which in turn means if you do something "reasonable" like download
Microsoft OpenJDK and place it into `$HOME/android-archives` -- so
that `xaprepare` doesn't need to download it *again* -- then the
provisioned JDK will be *unusable*.  Which makes @jonpryor sad.

Update `Step_InstallAdoptOpenJDK.MacOS.cs` to run
`xattr -d -r com.apple.quarantine $HOME/android-toolchain/jdk-21`.
This will *delete* the offending extended attribute, allowing e.g.
`javac` to run without error.

[^0]: Which versions?  ¯\\_(ツ)_/¯
