使用PowerMock会导致java.lang.VerifyError异常

Question

以下操作会在运行时导致异常：

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);
    }
}

java.lang.VerifyError：操作数堆栈上的类型错误异常详细信息：location：com/sun/net/httpserver/spi/httpserverprovider$1.run()ljava/lang/object；@27:invokestatic原因：类型“sun/net/httpserver/defaulthttpserverprovider”（当前帧，堆栈[0])不能分配给“com/sun/net/httpserver/spi/httpserverprovider”当前帧：bci:@27标志：{}locals：{“com/sun/net/httpserver/spi/httpserverprovider$1”}堆栈：{“sun/net/httpserver/defaulthtserverprovider”}字节码：0x0000000:b800 2599 0007 b800 27b0 b800 2699 0007 0x0000010:b800 27b0 bb00 1b59 b700 2ab8 0028

我认为该异常与PowerMock版本有关，因为删除@runwith(PowerMockRunner.class)行会使“测试”无一例外地运行。

知道那里出了什么问题吗？

如果您使用的是Java7，则可以使用“-xx：-usesplitverifier”作为JVM的参数来避免StackMap帧。
