1. Why are TimerTasks Runnable?    coderanch.com

The documentation on the Timer class implies that all TimerTasks queued to the timer are run in the Timer's thread, sequentially. (That's why Timer does not make real time guarantees.)

7. Threads - TimerTask - Basic problem    forums.oracle.com

Hi, although I haven't tried this solution, but maybe you do not have to "pause" the timer, but instead cancel and reschedule it.

Bye.
