JBOSS7部署EAR出现 java.lang.VerifyError

[fashchina]

EAR中，有EJB和WAR工程，war中的servlet调用EJB提示下面错误：
GatewayService threw exception: java.lang.VerifyError: (class: xxx/xxx/xxx, method: init signature: ()V) Incompatible object argument for function call
在EAR的LIB目录下，存在包含xxx/xxx/xxx的jar，并且初步进行check,没有发现存在相同名称的类。xxx/xxx/xx部分代码如下：
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.PrintStream;
import java.io.Serializable;

public class MessageObject
implements MsgConstant, Serializable
{
private DOMParser parser = new DOMParser();
private Document document;
private DocumentBuilder builder = null;
private Element root;
private Node header = null;
private Node extAttrs = null;
private Node request = null;
private Node response = null;
private Node body = null;
private boolean bindingRequest = false;
static Class class$0;
public MessageObject()
{
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
try {
this.builder = factory.newDocumentBuilder();
DOMImplementation impl = this.builder.getDOMImplementation();
this.document = impl.createDocument(null, "Message", null);

this.root = this.document.getDocumentElement();

this.header = setChildValueByName(this.root, "", "Header");
this.body = setChildValueByName(this.root, "", "Body");

this.extAttrs = setChildValueByName(this.header, "", "ext_attributes");

this.request = setChildValueByName(this.body, "", "request");

this.response = setChildValueByName(this.body, "", "response");

impl = null;
this.builder = null;
}
catch (Exception e) {
e.printStackTrace();
}
}
public MessageObject(byte[] bytesinput)
throws Exception
{
ByteArrayInputStream bais = new ByteArrayInputStream(bytesinput);
InputSource ins = new InputSource(bais);
ins.setEncoding("UTF-8");
this.parser.parse(ins);
bais.close();
ins = null;
init();
}
在调用 MessageObject(byte[] bytesinput)构造函数出现上面的错误，无解。。。

初步判断是类加载器问题，根据网上资料加了
jboss-app.xml和jboss-web.xml（前者放在ear压缩包中的META-INF目录下，后者是放到WAR包中META-INF目录下）

咋就没人遇到呢

GatewayService threw exception: java.lang.VerifyError: (class: xxx/xxx/xxx, method: init signature: ()V) Incompatible object argument for function call 是参数类型不匹配 ，看看调用ejb的代码怎么写的

[tianfang]

还有，不同项目/jar的编译的jdk版本，也可能导致这样的问题

这个问题，看来我是找不到我想要的答案了
