maven shade illegalstateexception-缺少必需的类信息

我刚刚使用javafx和hibernate构建了一个应用程序，它在intellij上构建和运行得非常完美，所以我选择使用maven shade plugin生成一个“胖jar”，因为我使用了一些带有自动模块名的库，所以我不能使用jlink。
jar创建得很好，它正确地加载了初始屏幕，但是当它试图连接到我的数据库时，特别是这一行是有问题的（jpautil）。java:19);

factory = Persistence.createEntityManagerFactory(persistenceUnit, properties);

我得到以下例外情况；

我知道语法是正确的，正如我之前提到的，它在ide上正确运行，所以我怀疑shade生成的jar文件中缺少了一些东西，但是我已经花了将近3天的时间在这上面了，我根本找不到原因。stacktrace上显示的信息没有多大帮助，至少我没有看到任何东西-我甚至查看了stacktrace上提到的所有类，它们似乎都在生成的jar上。希望这里的任何人都有类似的东西，或者在maven shade过程中可能比我更熟悉。任何帮助或点看将不胜感激。
有助于确定问题的其他文件如下：；
persistence.xml—其他属性是从代码上的xml文件加载的。

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.2" xmlns="http://xmlns.jcp.org/xml/ns/persistence"

            <property name="hibernate.format_sql" value = "false" />

我也有同样的问题。我试图将postgresqljdbc驱动程序版本降级到42.0.0。例外情况消失，一切正常。

我在使用spring时也遇到了同样的错误。version:5.2.7.release spring.boot.version：2.3.1.发布postgresql-version:42.2.16
从42.2.15开始的所有版本的postgres都会发生这种情况。版本42.2.14（或更早）对我来说很好。

通过从hibernate切换到openjpa，我成功地克服了这个问题。hibernate没有提供足够的信息来调试这个问题，当切换到openjpa时，我不得不将这个添加到pom.xml中；

<dependency>
     <groupId>org.apache.openjpa</groupId>
     <artifactId>openjpa-all</artifactId>
     <version>3.1.2</version>
</dependency>

shade创建了包含所有必需库的jar，并成功连接到数据库。
