looking for Derby's lock compatibility matrix

[Rick Hillegas <ri...@oracle.com>]

I seem to recall stumbling across this somewhere in the code or on the 
website long ago. But now I can't find it. It's the table which 
corresponds to "Compatibility Matrix for Granular Locks" in section 7.8 
of Gray and Reuter's Transaction Processing.

Thanks,
-Rick

In the code, RowLock.R_COMPAT and ContainerLock.C_COMPAT contain the
compatibility tables for row locks and container locks.
