Tried on Windows2000 and JDK build 1.6.0-ea-b15

See the following testcase

/*
 * TestRes.java
 * author Namita ,Seetharama
 */
import java.util.*;
import java.io.*;



class TestRes{
     public static void main(String args[]) {
         ResourceBundle re = ResourceBundle.getBundle("ASR", Locale.getDefault());
         System.out.println(re.getString("key1"));
         System.out.println(re.getString("key2"));
     }
}
Property file used for the above testcase is ASR_en_US.PROPERTIES with data as
key1=c:\unamita\namita.txt
key2=c:\namita\namita.txt

Output:
Exception in thread "main" java.util.MissingResourceException: Can't find bundle for base name ASR, locale en
        at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:837)
        at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:806)
        at java.util.ResourceBundle.getBundle(ResourceBundle.java:577)
        at TestRes.main(TestRes.java:12)


This Exception is misleading to the user as resource is in the same directory and available.
If we remove "key1" from Properties file it executes without exception.

If the same Property file is used with PropertyResourceBundle class throws different Exception. See the following testcase.

import java.util.*;
import java.io.*;

class TestRes1{
    
     public static void main(String args[]) throws Exception {
         
         //ResourceBundle re = ResourceBundle.getBundle("ASR", Locale.getDefault());
         ResourceBundle re = new PropertyResourceBundle(ClassLoader.getSystemClassLoader().getResourceAsStream("ASR_en_US.PROPERTIES"));
         
         System.out.println(re.getString("key1"));
         System.out.println(re.getString("key2"));
     }
}

The Output:
Exception in thread "main" java.lang.IllegalArgumentException: Malformed \uxxxx encoding.
        at java.util.Properties.loadConvert(Properties.java:492)
        at java.util.Properties.load(Properties.java:331)
        at java.util.PropertyResourceBundle.<init>(PropertyResourceBundle.java:96)
        at TestRes1.main(TestRes1.java:11)

ResourceBundle throws the same exception even when locale is not set properly.
