 As I have already pointed out, however broken /proc emulation might be
 this is a problem with the postinstall script in the package, NOT the
 kernel.
 
 You can't build classes.jsa using the server VM, you must use the client VM.
 Allowing the java binary to choose the VM is asking for trouble. Add -client
 to the command line arguments and the problem goes away.
