Fail to restTemplate create with @PowerMockIgnore in powermock

Question

I need a powermock for private method test.
It is working well if I use only @RunWith(PowerMockRunner.class) without @PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class).

I need to use @PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class) for @autowired. But It doesn't fail to start.

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyConfig.class}) 
@SpringBootTest
public class SpringPowerMockTest {

}

Threfore I add this through https://github.com/powermock/powermock/issues/864

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyConfig.class}) 
// I added this
@PowerMockIgnore({"javax.net.ssl.*", "org.slf4j.*", "javax.parsers.*", "ch.qos.logback.*", 
"jdk.xml.internal.*", "com.sun.org.apache.xerces.*", "javax.xml.*", "org.xml.*", 
"javax.management.*"})
@SpringBootTest
public class SpringPowerMockTest {

    @Test
    public void test() {
      //success
    }

}

It was working well.

Therefore, I started to write code for test

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyConfig.class}) 
@PowerMockIgnore({"javax.net.ssl.*", "org.slf4j.*", "javax.parsers.*", "ch.qos.logback.*", 
"jdk.xml.internal.*", "com.sun.org.apache.xerces.*", "javax.xml.*", "org.xml.*", 
"javax.management.*"})
@SpringBootTest
public class SpringPowerMockTest {

    @Test
    public void initalize() throws IOException {
        RestTemplate restTemplate = new RestTemplate();
        .....
    }


}

But I couldn't start with this error message

I don't know why I can't create RestTempleate. and I don't know @PowerMockIgnore

I solved that though adding code under line. But I can't understand what was cause.

com.sun.org.apache.xalan.internal.xsltc.trax.*

This is code which powermock a method

import static org.junit.Assert.*;
import static org.mockito.ArgumentMatchers.*;
import static org.powermock.api.mockito.PowerMockito.*;

import java.io.File;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PowerMockIgnore;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import org.powermock.modules.junit4.PowerMockRunnerDelegate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.stereotype.Component;
import org.springframework.test.context.junit4.SpringRunner;

import lombok.AllArgsConstructor;
import lombok.Data;


@SpringBootTest
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringRunner.class)
@PrepareForTest(PowerMockTarget.class)
@PowerMockIgnore({"com.sun.org.apache.xerces.*", "javax.xml.*", "javax.xml.transform.*", "org.xml.*", "javax.management.*", "javax.net.ssl.*", "com.sun.org.apache.xalan.internal.xsltc.trax.*"})
public class PowerMockTest {

    @Test
    public void mockStaticMethod() throws Exception {
        File fileMock = mock(File.class);
        when(fileMock.exists()).thenReturn(true);

        whenNew(File.class.getConstructor(String.class)).withArguments(anyString()).thenReturn(fileMock);
        
        PowerMockTarget target = new PowerMockTarget();
        assertEquals(target.isFileExist(), true);

        assertEquals("My bean message", message.getContent());
    }
}

@Data
@AllArgsConstructor
class MessageForTest{
    private long id;
    private String content;
    
}


@Data
@AllArgsConstructor
class MessageForTest{
    private long id;
    private String content;
    
}

Powermocked target code.

import java.io.File;

public class PowerMockTarget {

    public boolean isFileExist() {
    
        if(!new File("filename").exists()) {
          throw new RuntimeException();
        }
        return true;
    }
}

Fail to restTemplate create with @PowerMockIgnore in powermock
