Not sure what is wrong - o.n.m.debugger.jpda.breakpoints.PersistenceManager.storeBreakpoints() listens on document changes (ok) and schedules a task for storing breakpoints (probably?), which ends up in o.o.u.RP$SlowItem.<init>()...
Wrong is RP$SlowItem.<init>()! But since this occurs almost everywhere, I've prepared a workaround for that in issue #173932.
