        * libraries/javalib/vmspecific/java/lang/VMClassLoader.java: Removed.

        * libraries/javalib/vmspecific/Makefile.am (dist_vminterface_JAVA): Removed /java/lang/VMClassLoader.java.

        * libraries/clib/native/ClassLoader.c (java_lang_VMClassLoader_getPrimitiveClass):
        Renamed from java_lang_VMClassLoader_getPrimitiveClass0.
        Throw NoClassDefError if primitive class is not found.
