Dag H. Wanvik commented on DERBY-6124:
--------------------------------------
Using the program below to extract the generated (default UUID), I see it has
changed in 10.10.
I don't know this test well enough to say if it is expected that we read a
price object generated
pre 10.10 with 10.10.
Price UUID in 10.10: 1827170030595550895
Price UUID in 10.9: 0102726277789621992
Price UUID in 10.8: 0102726277789621992
