Laszlo Attila Toth commented on TEZ-4384:
-----------------------------------------
[~abstractdog] It's not related to Java 17, but I found it during working on
the Java 17 compatibility. The code tried to alter System.getenv directly,
which doesn't work in Java 17. As I tried to figure out the intention of the
code I noticed that the class has only one client, only the test class uses it.
Strangely not long after the introduction it's usage is dropped in TEZ-1837,
but the actual class remained in the code base.
