add Mac Java paths to depfile_parsing_sandbox

[matt-phylum]

MacOS normally installs JDKs in these locations: https://nanova.me/posts/macos-jdk-path

That page also references a ~/.jenv directory which I did not add. I don't know if there's any reason not to add it.

Looks reasonable to me. Is an exception for the JAVA_HOME environment variable also needed? Or, will having java on the PATH be enough to find and use the JDK?

[matt-phylum]

Is JAVA_HOME being removed from the environment variables? I would expect all the existing Java-related exceptions here to fail if we needed it and it was being removed. I don't have JAVA_HOME set in my environment, but mvn is a shell script that sets JAVA_HOME before calling the real mvn...

It looks like, at least for Maven, JAVA_HOME is not required. If JAVA_HOME is not set it does a command -v java to locate the JRE.
