     Are you sure startThreads() is creating and starting brand-
new Threads each time it's called, not re-using old Threads?
To put it another way, are you sure stopThreads() actually stops
all the old Threads and waits for them to finish stopping (and
then clears its "running workers" list)?

     I cannot imagine how a newly-created Thread would find itself
in the interrupted state before anything interrupts it.  Is there
some other part of your program that interrupts Threads when it
shouldn't?
