Class Overview
SelectorProvider is an abstract base class that declares methods for
providing instances of DatagramChannel, Pipe,
Selector , ServerSocketChannel, and
SocketChannel. All the methods of this class are thread-safe.
A provider instance can be retrieved through a system property or the
configuration file in a jar file; if no provider is available that way then
the system default provider is returned.

provider()
Gets a provider instance by executing the following steps when called for
the first time:
- if the system property "java.nio.channels.spi.SelectorProvider" is
set, the value of this property is the class name of the provider
returned;

"java.nio.channels.spi.SelectorProvider" in META-INF/services of a jar
file valid in the system class loader, the first class name is the
provider's class name;
- otherwise, a system default provider will be returned.
