Anyone has StandardClassLoader.class ?? Correction: i meant beta 5

[Matthias Schiffer]

Hi!
 
 Please people tell me whether someone here own the
 StandardClassLoader.class of beta 4. Thank you very much. I have 
several problems compiling my programs because this file is missing and 
the src-code seems to be incorrect or my classpath is incorrect, but  
the classpath consists of about 11 elements.....
