I understand that your program is huge and very difficult to trim down
to a one page program that still exhibits the behaviour you are
encountering, but if you could do that, it would be much more possible
to find out the cause.
Meanwhile, I worry more about the following:

This is impossible. If a thread T calls a method M, M is run in T, no
matter which object or class M belongs to. Unless M is or leads to a
notify(), there is no way M wakes up any other thread. Even when M
leads to a notify(), the waken thread will just resume what it has
been doing; M is still run by T, not the waken thread.
Thus, if by "dummy method" you really mean it, it cannot wake up any
thread, period.
What I think really happened is that your timer thread T is doing all
the work, giving you the impression that the program is making
progress, while all other threads are still blocked and not waken.
