带有JAXB Random ClassCastException ..的Netbeans无法转换为com.sun.xml.bind.v2.runtime.reflect.Accessor

Question

我已经从SOAP服务下载了Soap消息，并试图通过返回下载的消息来模拟Soap服务。以下代码显示了我如何将Soap消息解组到所需的Response中

    public static DataClientType unmarshallFile(String fileName) throws Exception {
    XMLInputFactory xif = XMLInputFactory.newFactory();
    XMLStreamReader xsr = xif.createXMLStreamReader(ClientSampleSoapResponseData.class.getResourceAsStream(fileName));
    xsr.nextTag(); // Advance to Envelope tag
    xsr.nextTag(); // Advance to Header
    xsr.nextTag(); // Advance to Body tag
    xsr.nextTag(); // Advance to getClientByAccountResponse
    xsr.nextTag(); // Advance to content of getClientByAccountResponse

    JAXBContext jc = JAXBContext.newInstance(GetClientByAccountResponse.class);
    Unmarshaller unmarshaller = jc.createUnmarshaller();
    JAXBElement<GetClientByAccountResponse> je = unmarshaller.unmarshal(xsr, GetClientByAccountResponse.class);

    return je.getValue().getClientDataContract();
}

但是我一直得到这个ClassCastExeption，它是随机发生的。经过多次测试迭代后，它开始发生。有时清理并修复它，但有时不起作用。

java.lang.ClassCastException: com.x.X.X.X.GetClientByAccountResponse$JaxbAccessorF_clientDataContract cannot be cast to com.sun.xml.bind.v2.runtime.reflect.Accessor
at com.sun.xml.bind.v2.runtime.reflect.opt.OptimizedAccessorFactory.instanciate(OptimizedAccessorFactory.java:188)
at com.sun.xml.bind.v2.runtime.reflect.opt.OptimizedAccessorFactory.get(OptimizedAccessorFactory.java:180)
at com.sun.xml.bind.v2.runtime.reflect.Accessor$FieldReflection.optimize(Accessor.java:256)
at com.sun.xml.bind.v2.runtime.property.SingleElementNodeProperty.<init>(SingleElementNodeProperty.java:90)

我已经尝试了其他在线建议，例如恢复到旧的jaxb版本以及在maven编译器配置中使用认可的文件夹，但是仍然会发生

有什么想法可能导致它以及可能的解决方案？

感谢你

用以下代码解决

@BeforeClass
public static  void init(){ 
    System.setProperty( "com.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize", "true");
}

@AfterClass
public static void revert(){ 
    System.getProperties().remove("com.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize");
}

也可以使用以下命令在JVM上设置参数

-Dcom.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize=true
