A DESCRIPTION OF THE REQUEST :
I just stumbled across yet another java.lang.NoClassDefFoundError question at the JDC:

java.lang.NoClassDefFoundError: Test (wrong name: package/Test)

If one knows what's going on, this is enough to tell that the package name was omitted and the error makes a suggestion. But the text for the suggestion is a little misleading, especially for beginners that are most likely to stumble across it. Even I still get confused about it from time to time.

The text in the parenthesis implies that "package/Test" is the wrong name, but actually, it's the correct one, and loading the class just using "Test" was wrong.

JUSTIFICATION :
I think especially beginners will benefit from getting a more helpful error message.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
An error message similar to
java.lang.NoClassDefFoundError: Test (Did you mean package.Test? Use fully qualified class names.)
would be more helpful to finding not only the cause of the problem, but also a solution.
ACTUAL -
Produces a confusing error message:
java.lang.NoClassDefFoundError: Test (wrong name: package/Test)

So is Test incorrect, or package/Test? It's not easy to tell given this text. It actually (wrongly) emphasizes that package/Test would be the problematic name.
