使用PowerMock会导致java.lang.VerifyError异常

Question

以下内容在运行时导致异常:

import com.sun.net.httpserver.HttpServer;
import org.junit.runner.RunWith;
import org.powermock.modules.junit4.PowerMockRunner;
import java.net.InetSocketAddress;

@RunWith(PowerMockRunner.class)
public class MainTest {
    @org.junit.Test
    public void main() throws Exception {
        HttpServer.create(new InetSocketAddress(8080), 0);
    }
}

例外:

我认为该异常与PowerMock版本有关,因为删除该行@RunWith(PowerMockRunner.class) 会使"测试"运行毫无例外.

知道那里有什么问题吗？

如果您使用的是 Java 7，则可以使用“-XX:-UseSplitVerifier”作为 JVM 的参数来避免 StackMap 帧。
