The loop was only required to filter SecurityException so you change this to `return sl.findFirst().orElse(null);`

src/java.base/share/classes/java/nio/channels/spi/SelectorProvider.java line 113:

Same thing as AsynchronousChannelProvider here, the loop goes away, it can be replaced with `return sl.findFirst().orElse(null);`
