Use external classes in @run driver

Thank you! I got the idea.
code and document are correct. My understanding is right.
Even my initial change was right. After I delete those files in test/lib/*, I left the empty directory test/lib in hotspot/test.
That's why jtreg had trouble to pick up the classes suggested from external.lib.roots and @library. Lesson learned.

Yes, this is the primary use case for external.lib.roots.
You may need to adjust the order of items in external.lib.roots,
especially as you seem to have an anti-pattern going on, of one library
inside another, as indicated by
Poking around the 8u/8u forest, the reference to ../../jdk seems
questionable as that seems to indicate the the top of the jdk repo. That
being said ...
Poking around a bit more, I see there is
8U-FOREST/jdk/test/lib/jdk/test/lib, and that FileInstaller.java is in
`package jdk.test.lib` which means that the package root for the class
This means that you need an entry in external.lib.roots and a @library
that together form the path ../../jdk/test/lib
Can you find any other tests in the hotspot test repo that are using
external.lib.roots? I'm guessing maybe not, since I don't see an entry
in the hotspot/test TEST.ROOT file.
Separately, I will investigate why jtreg is reporting an invalid value
for the number of seconds it took.
