safeExecute

protected static void safeExecute(java.lang.Runnable task)

Try to execute the given Runnable and just log if it throws a Throwable.

runTask

protected static void runTask(java.lang.Runnable task)

lazyExecute

@UnstableApi
public void lazyExecute(java.lang.Runnable task)

Like Executor.execute(Runnable) but does not guarantee the task will be run until either a non-lazy task is executed or the executor is shut down.

The default implementation just delegates to Executor.execute(Runnable).
