Alexey Loubyansky commented on JBAS-5231:
-----------------------------------------

Yes, it looks good to me even w/o the SelectHiSql. Of course, we need proper tests for this. But fixing "JBAS-3266 HiLoKeyGenerator is not cluster-safe" I seem to have not realized all the things that it fixed. Proper tests mean running a couple of JBoss instances and using key generators backed by the same db and table.
