I've tested it and the way jBPM is providing all mysql setup data it works like a charm. I noticed one difference though. I use the org.hibernate.dialect.MySQLInnoDBDialect instead of what you use. Since I'm no DB expert I do not know the difference not do I intent to find out, but you might give it a try.
