Hi,
    The files that your error message mention (e.g. util.FileReader, 
util.SegmentFileReader, etc.) are no loner part of Kepler. I thus 
suspect that you may have checked out Kepler without the '-P' switch 
which removes empty directories. Empty directories in the 
$Kepler/src/actors/ directory will cause errors like yours (and CVS will 
create empty directories there if the -P (prune) is not used in 
checkout/update.
