A DESCRIPTION OF THE PROBLEM :
Executors. returns an ExecutorService which uses a LinkedBlockingQueue. As seen in bug 6806875 LinkedBlockingQueue has a "Young" memory leak. This behaviour is thus seen with any use of the ExecutorService.
It seems reasonable to me to create a long running ExecutorService to run many tasks over time and to expect its memory usage to not behave like this.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
This bug can be reproduced always.
