Creates fixed thread pool executor of specified size with daemon threads.

Parameters:

threadNamePrefix - prefix for thread names

poolSize - size of the thread pool

Returns:

new thread pool

Since:

8.1.2

newFixedDaemonExecutor

@NotNull
public static ExecutorService newFixedDaemonExecutor(@NotNull
