org.hibernate.exception.ConstraintViolationException: could not delete:

异常描述：

org.hibernate.exception.ConstraintViolationException: could not delete:

调用方法RepositoryService.deleteDeploymentCascade(deploymentId)时报org.hibernate.exception.ConstraintViolationException: could not delete:

[org.jbpm.pvm.internal.model.ExecutionImpl#1]

解决：

连接Mysql5时，jBPM4运行到 End结点时的错误，把 hibernate.dialect 改为 org.hibernate.dialect.MySQLInnoDBDialect 就Ok了！
