I know I can use a fixedThreadPool to limit the amount of threads my program uses at one time. If I use a cachedThreadPool and could run 10,000 threads, will the JVM schedule them appropriately so not too many are running at the same time?
Does the JVM limit the number of threads an Executor can run?
