    Attachment: derby-2149-1b.diff

Uploading a new patch. The problem with the previous one was a mix-up of two variable names.
Have run derbyall and the JUnit tests with one failure in store/readlocks.sql (diff similar
to http://www.multinet.no/~solberg/public/Apache/Derby/testlog/Linux-2.4.21-27.ELsmp_i686-i686/240441-storeall_diff.txt).
