Using Classpath on the Sun VM

[Blake Meike]

Hi,
  I have a largish application that runs well under the Sun JRE.  I'm 
interested in porting it to Kaffe/Classpath.  My first attempts have 
failed in some surprising ways, and I'm anticipating an extended struggle ;)

  I would like to know if anyone has tried using the Classpath class 
libraries on the Sun JVM.  I'm hoping this is possible so that I can use 
my standard debugging environment (Eclipse) during the porting process.

  I've tried a few obvious things with -Xbootclasspath:... with no 
success.  At this point, am failing at:

Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/ref/FinalReference

  If anyone else has tried this and either knows how to do it, or knows 
that it is impossible, I'd love to hear about it.

Thanks
  Blake Meike
