public class JavaServer extends GatewayServer
This class extends GatewayServer by implementing a new threading model: a thread always use the same connection to the other side so callbacks are executed in the calling thread.
For example, if Java thread 1 calls Python, and Python calls Java, the callback (from Python to Java) will be executed in Java thread 1.

entryPoint - The entry point of this Gateway. Can be null.port - The port the GatewayServer is listening to.connectTimeout - Time in milliseconds (0 = infinite). If a GatewayServer does
not receive a connection request after this time, it closes
the server socket and no other connection is accepted.readTimeout - Time in milliseconds (0 = infinite). Once a Python program is
connected, if a GatewayServer does not receive a request
(e.g., a method call) after this time, the connection with the
Python program is closed.customCommands - A list of custom Command classes to augment the Server
features. These commands will be accessible from Python
programs. Can be null.pythonClient - The Py4JPythonClientPerThread used to call Python.public JavaServer(Object entryPoint, int port, int connectTimeout, int readTimeout, List<Class<? extends Command>> customCommands, Py4JPythonClientPerThread pythonClient, String authToken)
