> DRLVM throws ClassNotFoundException instead of NoClassDefFoundError if it fails to load
class from bootclasspath.
> I did not find the exact place in specification saying it is wrong behavior, still 
> 1. JVMS operates with NoClassDefFoundError only in case the loading process failed. 
> 2. both Sun & JRockit java throws NoClassDefFoundError from the test below.
> To reproduce the issue, please do the following:
> a) compile attached Test.java (this produces Test.class, SubClass.class and SuperClass.class)
> b) remove SuperClass.class 
> c) run test with SubClass in bootclasspath, e.g.
>   
>     $ ls -1 *.class
>     Test.class SubClass.class
>     $ java -Xbootclasspath/a:. Test
> The output on Reference Implementation:
>     PASSED: got NoClassDefFoundError...
>     Note: run Test with SubClass in bootclasspath...
> The output on Harmony DRLVM (with -showversion key):
>     Apache Harmony Launcher : (c) Copyright 1991, 2006 The Apache Software Foundation
or its licensors, as applicable.
>     java version "1.5.0" 
>     pre-alpha : not complete or compatible
>     svn = r486063, (Dec 12 2006), Windows/ia32/msvc 1310, debug build
>     http://incubator.apache.org/harmony
>     FAILED: got ClassNotFoundException...
> Thanks
