[cp-patches] small path to remove unused classes

[Dalibor Topic]

Hi all, as discussed in 
http://comments.gmane.org/gmane.comp.java.classpath.devel/5072

I've removed the three unused classes I spotted in my kaffe/classpath 
syncing.

2005-02-01  Dalibor Topic  <address@hidden>

        * gnu/java/beans/EmptyBeanInfo.java,
        gnu/java/beans/info/ComponentBeanInfo.java,
        gnu/java/lang/SystemClassLoader.java:
        Removed unused files.

cheers,
dalibor topic
