Description

import ognl.Ognl;

import ognl.OgnlContext;

import com.opensymphony.xwork2.util.OgnlValueStack;

import java.io.Serializable;

public class OGNLDebug {

public static void main(String[] argv)

{ Result result = new Result(); OgnlValueStack stack = new OgnlValueStack(); stack.push(result); stack.setValue("example.param", "0"); stack.setValue("brokenExample.param", "0"); System.out.println("example.param: " + result.getExample().getParam() ); System.out.println("brokenExample.param: " + result.getBrokenExample().getParam() ); }

}

class Result {

private Example example = new Example();

private BrokenExample brokenExample = new BrokenExample();

public Result() {

}

public Example getExample()

{ return example; }

public void setExample(Example example)

{ this.example = example; }

public BrokenExample getBrokenExample()

{ return brokenExample; }

public void setBrokenExample(BrokenExample brokenExample)

{ this.brokenExample = brokenExample; }

}

class Example {

private Integer param;

public Integer getParam()

{ return param; }



public void setParam(Integer param) { this.param = param; }

}



interface Cracker<T extends Serializable>{ T getParam(); void setParam(T param); }



class BrokenExample implements Cracker<Integer>{

private Integer param;



public Integer getParam() { return param; }

public void setParam(Integer param)

{ this.param = param; }

}

Expected result

example.param: 0

brokenExample.param: 0

Actual result:

example.param: 0

brokenExample.param : null
