my java bean define:

public class Request implements Serializable{
	private String id;
	private String instance;
	private String _interface;
	private String method;
	private Object[] params;
      public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getInstance() {
		return instance;
	}
	public void setInstance(String instance) {
		this.instance = instance;
	}
	public String getInterface() {
		return _interface;
	}
	public void setInterface(String _interface) {
		this._interface = _interface;
	}
	public String getMethod() {
		return method;
	}
	public void setMethod(String method) {
		this.method = method;
	}
	public Object[] getParams() {
		return params;
	}
	public void setParams(Object[] params) {
		this.params = params;
	}
}

my json string is:

{"id": "439a3213-e734-4bf3-9870-2c471f43d651", "instance": "v1", "interface": "com.xxx.aplan.UICommands", "method": "start", "params": ["tony"], "@type": "com.xxx.dcp.rpc.core.Request"}

but when set property 'params' throws an error because: JSONArray can not be set to params

问题是无法重现问题，可以提一下更完整的堆栈信息么？
