Finally a test case for the ClassNotFound

[Mark Roos]

The error I see is that at random times when I am executing Smalltalk on 
jvm I get occasional a ClassDefNotFound
during an InvokeExact.  Usually when I am doing a demo.  After lots of 
trying I have a test which fails every time
for me.  When it fails the stack depth varies from 1 or 2 invokeExacts to 
lots.  And its never in the same place or
aligned with anything I can see.  Not allways the same method of mine for 
instance.

This test seems to cause the following error on server versions of JDK 7 
but not windows client. And seems to happen
when hotspot gets aggressive on code which was running.  Once it happens 
it continues on that call site.
Tried on Windows XP, 7 and recent OSX port.  Also on the 8/8 Bsd Port from 
Stephen but it has other
errors.

Its at ftp.roos.com  user=javadev pw=mlvm  RtalkTest.zip.  The .gob files 
are the smalltalk source code
and the libs are optional debug agents ( not used by this test).

when run  ( java -server -cp RtalkTest.jar ri/experiment2/RtalkTest )  it:
        reads and loads the smalltalk image from the .gobs
        does an initial Hanoi recursion
        does lots of string handling similar to socket rad writes
        lists the GWT depths
        invalidates the call sites
        runs some stuff again to re bootstrap the sites
        runs the same Hanoi again.

Takes a minute or so on my mac.  Fails about half way

Thrashes pretty well all of the facets I am using and generates some 
pretty long GWT chains.

Other than the trap its interesting that the second Hanoi is much slower 
than the first.

Let me know how I can help
