Looks good. Given there are other even longer lines, maybe you would want to join the comment lines 523 and 524?

Yep, it wouldn't always be verbatim correct, e.g. if jdk/jdk advances to jdk16, it'll be wrong. However maybe you could still strip the "open" from the parameter "TEST=open/test/jdk/tools/launcher/JliLaunchTest.java" in line 66? I guess that would be most correct for OpenJDK...

But anyway, the new webrev looks good. No need for further update/discussion from my end. The sooner it's in the merrier I am ��
