Product Version = NetBeans IDE Dev (Build 201110120600)
Operating System = Windows XP version 5.1 running on x86
Java; VM; Vendor = 1.7.0
Runtime = Java HotSpot(TM) Client VM 21.0-b17

- create new wab app, using CDI, JSF
- create class:
package beans;

/**
 *
 * @author muellermi
 */
public class NameValue {
    private String _name;
    private String _value;

    public String getName() {
        return _name;
    }

    public void setName(String name) {
        this._name = name;
    }

    public String getValue() {
        return _value;
    }

    public void setValue(String value) {
        this._value = value;
    }
}

- create test:
/*
 * To change this template, choose Tools | Templates and open the template in
 * the editor.
 */
package beans;

import static org.junit.Assert.assertEquals;
import org.junit.Test;

/**
 *
 * @author muellermi
 */
public class NameValueTest {
    
    @Test
    public void testName() {
        System.out.println(" test Name");
        NameValue instance = new NameValue();
        String expResult = "John Doe";
        instance.setName(expResult);
        assertEquals(expResult, instance.getName());
    }


}
- in project tree, on project WebAplication [or ChoosenName], right click, test
--> test passes
- in project tree on test file, right click, test file
--> test fails "unknown caused an Error: Forked Java VM exited abnormally..."

notes: 
- no such strange behavior for Java (non web) application
- single test had been ok with older build (today I only checked with 20111012 and 20101010, older builds are de-installed. Thus I don't know since which build ther is such a malfunction)
