InetAddress: Cannot inject classes into the bootstrap class loader

[MrCreosote]

What steps will reproduce the problem?

Running EqualsVerifier on a class with an InetAddress field.

Changing the code below to wrap a String vs. an InetAddress makes the test pass.

What is the code that triggers this problem?

import java.net.InetAddress;

import nl.jqno.equalsverifier.EqualsVerifier;

public class TempTest {

	final InetAddress ia;

	private TempTest(InetAddress ia) {
		this.ia = ia;
	}

	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + ((ia == null) ? 0 : ia.hashCode());
		return result;
	}

	@Override
	public boolean equals(Object obj) {
		if (this == obj) {
			return true;
		}
		if (obj == null) {
			return false;
		}
		if (getClass() != obj.getClass()) {
			return false;
		}
		TempTest other = (TempTest) obj;
		if (ia == null) {
			if (other.ia != null) {
				return false;
			}
		} else if (!ia.equals(other.ia)) {
			return false;
		}
		return true;
	}
	
	public static void main(String[] args) {
		EqualsVerifier.forClass(TempTest.class).usingGetClass().verify();
	}
	
}

What error message or stack trace does EqualsVerifier give?

What did you expect?

The test to pass.

Which version of EqualsVerifier are you using?

2.2.1

Please provide any additional information below.

None. Thanks yet again for EV, it's great.

[jqno]

Thanks for the detailed report. I was able to reproduce it. I'll let you know as soon as I have a fix.

[jqno]

I've just released version 2.2.2, which contains a fix.

[MrCreosote]

Wow, that's quite the response time there. Thanks! I'll try it out when it's up on maven repo.
