Unfortunately it's a bug with the JVM implementation, not in Mckoi.  Are 
your installations on win32 or linux?  Have you tested with other JVMs? 
  You could test if the online backup reproduces this problem with your 
JVM/OS by repeating the backup function and see if the error occurs.

I do not suggest you COMPACT tables if it is not necessary to do so. 
COMPACT should only be used if you insert and delete data from a table 
and then you need the file space reclaimed to the file system.  We have 
installed several installations of Mckoi that have never used the 
COMPACT function.
