Summary

0000340: MethodExpr.evalObject bug. fixed in 3, please backport.

Description

RSN-384
class implementation visibility causes IllegalAccessException in MethodExpr.evalObject

fix:
in MethodExpr.evalObject
call method.setAccessible(true);
prior to calling
return method.invoke(aObj, objs);

This has been fixed in 3. Please backport.

Note: Using Resin 2.1.x with JDO is nearly impossible as JDO queries returning collections are required to return unmodifiable collections. Using the query results will often cause the following error (or similar).

--------begin test case---------

import com.caucho.el.Expr;
import com.caucho.el.MapVariableResolver;
import com.caucho.jsp.el.JspELParser;

import java.util.HashMap;
import java.util.Collections;
import java.util.HashSet;

public class Test1 {

  public static void main(String[] args) {

    try {
      Expr expr = new JspELParser("${c.size()}").parse();
      HashMap map = new HashMap();
      //the implementation of UnmodifiableSet is not public.
      map.put("c", Collections.unmodifiableSet(new HashSet()));

      Object o = expr.evalObject(new MapVariableResolver(map));
      System.out.println(o);

    } catch (Throwable e) {
      e.printStackTrace(); // todo - fix
    }
  }
}
