fastjson反序列化异常类时丢失信息

[zackhu135]

自定义的一些字段并没有被反序列化：
我定义的类内容如下：

public class MyException extends RuntimeException{
    private static final long serialVersionUID = 7815426752583648734L;
    private long code;

    public MyException() {
        super();
    }

    public MyException(String message, Throwable cause) {
        super(message, cause);
    }

    public MyException(String message) {
        super(message);
    }

    public MyException(Throwable cause) {
        super(cause);
    }

    public MyException(long code) {
        super();
        this.code = code;
    }

    public MyException(long code, String message, Throwable cause) {
        super(message, cause);
        this.code = code;
    }

    public MyException(long code, String message) {
        super(message);
        this.code = code;
    }

    public MyException(long code, Throwable cause) {
        super(cause);
        this.code = code;
    }

    public void setCode(long code) {
        this.code = code;
    }

    public long getCode() {
        return code;
    }

    @Override
    public String toString() {
        return "MyException{" +
                "code=" + code +
                '}';
    }
}

MyException myException = new MyException(100,"error msg");
     str= JSON.toJSONString(myException);
序列化后str的内容为：
{
	"@type": "MyException",
	"code": 100,
	"localizedMessage": "error msg",
	"message": "error msg",
	"stackTrace": [{
		"className": "Main",
		"fileName": "Main.java",
		"lineNumber": 103,
		"methodName": "main",
		"nativeMethod": false
	},
	{
		"className": "sun.reflect.NativeMethodAccessorImpl",
		"fileName": "NativeMethodAccessorImpl.java",
		"lineNumber": -2,
		"methodName": "invoke0",
		"nativeMethod": true
	},
	{
		"className": "sun.reflect.NativeMethodAccessorImpl",
		"fileName": "NativeMethodAccessorImpl.java",
		"lineNumber": 57,
		"methodName": "invoke",
		"nativeMethod": false
	},
	{
		"className": "sun.reflect.DelegatingMethodAccessorImpl",
		"fileName": "DelegatingMethodAccessorImpl.java",
		"lineNumber": 43,
		"methodName": "invoke",
		"nativeMethod": false
	},
	{
		"className": "java.lang.reflect.Method",
		"fileName": "Method.java",
		"lineNumber": 606,
		"methodName": "invoke",
		"nativeMethod": false
	},
	{
		"className": "com.intellij.rt.execution.application.AppMain",
		"fileName": "AppMain.java",
		"lineNumber": 144,
		"methodName": "main",
		"nativeMethod": false
	}],
	"suppressed": []
}

但通过MyException myExceptionJson = JSON.parseObject(str,MyException.class);
反序列化后，得到的myExceptionJson的code字段并没有被反序列化出来。

追了一下源码，解析的时候把不是标准Exception信息的key-value单独存到了一个HashMap了，然后赋值的时候，没用上。改改就好。
