I'm trying to do a unit test on my socket server code. I'm using Mockito but it blows up when the SUT runs to the following line because this is a final method.

I'm new to PowerMock and I am trying to use it but I am facing various issues no matter what I tried. If someone can help review the following and offer some help that'd be great.

Here is the code used for testing.

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.mockito.Mockito;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.springframework.stereotype.Component;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;
import org.testng.IObjectFactory;
import org.testng.annotations.ObjectFactory;
import org.testng.annotations.Test;
import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.SocketAddress;
import java.nio.ByteBuffer;
import java.nio.channels.SocketChannel;
@ActiveProfiles("QuickTest")
@Component
@ContextConfiguration(classes = AppConfigQuickTest.class)
@PrepareForTest({SocketChannel.class, QuickTest.class})
public class QuickTest extends AbstractTestNGSpringContextTests {
    // An error occurred while instantiating class com.QuickTest: Could not initialize class org.apache.logging.log4j.util.PropertiesUtil
    // Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.apache.logging.log4j.util.PropertiesUtil

    // at org.apache.logging.log4j.LogManager.<clinit>(LogManager.java:60)
    // at com.QuickTest.<clinit>(QuickTest.java:32)
    private static final Logger logger = LogManager.getLogger("QuickTest");
    @ObjectFactory
    public IObjectFactory getObjectFactory() {
        return new org.powermock.modules.testng.PowerMockObjectFactory();
    @Test
    public void socketTest() throws IOException {
        int bytesWritten = 5;
        SocketChannel socketChannel = PowerMockito.mock(SocketChannel.class);
        SocketAddress socketAddress = new InetSocketAddress("abc.com", 12340);
        Mockito.when(socketChannel.getRemoteAddress()).thenReturn(socketAddress);
        Mockito.when(socketChannel.write((ByteBuffer) Mockito.any())).thenReturn(bytesWritten);
        // todo: socketChannel.register() is causing Mockito to throw null pointer exception because it's a final method
        Mockito.doNothing().when(socketChannel.register(Mockito.any(), Mockito.any()));
        // further stuff down here to setup and do test

First problem
It is having a problem with the following line.

This is the full stack trace.

Second problem
If I comment out the logger I am getting the following.

Third problem
If I remove the 'extends AbstractTestNGSpringContextTests' bit on the class I am still getting the following. At this point I'm not sure what else I can try.
