mysql - 错误 -4850 无效的模式名称 JPA/EJB，我该如何解决？

Question

当我启动 Tomee 服务器并尝试登录时，出现此错误

javax.ejb.EJBException: The bean encountered a non-application exception; nested exception is: 
    Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.7.4.v20190115-ad5b7c6b2a): org.eclipse.persistence.exceptions.DatabaseException

我的模式名称是“gmadb”，我不知道为什么会出现这个错误
