JBPM 5.3.1的问题

Question

在我目前的应用程序中，我升级了Spring、Hibenate和JBPM的jar

Spring3到Spring4.2

Hibernate3到Hibernate4

JBPM5.3.0到JBPM 5.3.1

但是在升级jar之后，我得到了下面的异常。

java.lang.IllegalArgumentException: Unknown entity: org.jbpm.persistence.processinstance.ProcessInstanceInfo

请帮我解决这个问题。

您的persistence.xml中似乎缺少ProcessInstanceInfo，但由于您已经将Spring和Hibernate都更新到了下一个主要版本，所以可能还有许多其他原因导致它无法工作。

我想知道为什么您使用几乎最新版本的Spring，而使用几年前的jBPM版本。即使是Spring6.4也不支持Spring4，但jBPM 6.5可能会支持它。
