The missing backslash means "-gc/g1/TestTimelyCompaction.java” will actually be interpreted as a test group name by jtreg, resulting in an empty test group. There is no TestTimelyCompaction.java test/file, so either it was not added, or it’s really supposed to be test/hotspot/jtreg/gc/g1/TestPeriodicCollection.java (which was added as part of the same change).

Looks good, and trivial.

Maybe someone should contact the original authors of the change regarding the possibly missing test.
