PropertyResourceBundle gives NullPointerException

Question

Hello,
I don't know if this is the right place to post, but it seems the nearest one to my Problem.
The Problem is, like stated in the Topic, PropertyResourceBundle gives me a NullPointerException when using it in an Applet.
First things first: I'm using JRE 1.5.0_03 under W2K.
I was trying to open a CachedRowSet in an Applet using
CachedRowSet crs = new CachedRowSetImpl();
That works fine in Rational Web Developer IDE (using Eclipse) with the AppletViewer. It also works fine when I write a little Test Class and invoke the creation of the CachedRowSet from the Commandline.
The Test Class is:
public class Tests {
     public static void main(String[] args) {
          System.out.println("Creating Rowset");
          try {
               CachedRowSet crs = new CachedRowSetImpl();
               System.out.println("Size of RowSet: " + crs.size());
          catch (Exception e) {
               System.out.println("Error: " + e.getMessage());
          System.out.println("Done");
When executing it via Commandline the Sizeoutput is 0 (like anticipated).
Ok....so far so good. Reading older comments on these Forums about CachedRowSet giving NullPointerExceptions I realized that it's not the CachedRowSet but the PropertyResourceBundle. So I decompiled JdbcRowSetResourceBundle.class with jad and got to the following Code:
propResBundle = new PropertyResourceBundle(Thread.currentThread().getContextClassLoader().getResourceAsStream("com/sun/rowset/RowSetResourceBundle.properties"));
Again, it works fine within Rational Web Developer.
But when I try to open it in a Browser with the Java Plugin I always get the following Error:
java.lang.NullPointerException
     at java.util.Properties$LineReader.readLine(Unknown Source)
     at java.util.Properties.load(Unknown Source)
     at java.util.PropertyResourceBundle.<init>(Unknown Source)
Before that, I do a System.out.print of the Classloader, which gives me:
Classloader: sun.plugin.security.PluginClassLoader@e28b9
Here's the whole trace:

I'm stuck and getting out of Ideas. Does anyone have had the same problem or knows a solution for it?
Thanks,
Carsten
