Is there jtreg support for this or are you proposing @library ../../../../../ ? I realize this might be a question for future steps but still useful to know where this is going.

The suggestion is to use "@library /../../test/lib”. Using an initial slash means that the path is relative to TEST.ROOT, not to the test itself. I’m not sure if this was intended in jtreg or if it just happens to work. I’m sure we can think of cleaner approach in the future.
