我认为问题在于Hibernate依赖于Javassist的旧版本。您应该使用3.23.1-GA：
<dependency> <!-- update Hibernate dependency on Javassist to 3.23.1 for Java 11 compatibility --> <groupId>org.javassist</groupId> <artifactId>javassist</artifactId> <version>3.23.1-GA</version></dependency>解决方法
我刚刚迁移到JDK 11，以便使用最新的JavaLTS版本。如果我将Eclipse中的执行JRE从10更改为11（然后才更改），则当我尝试运行测试时，会收到以下异常stacktrace（为了方便阅读，我删除了一些部分）。
请注意，如果我切换回jdk-10，一切都会按预期进行。显然，我使用Springboot和Hibernate作为我的ORM。我已经检查了http://in.relation.to/2018/09/13/using-hibernate-orm-with-jdk11/中的文章，并试图解决这些依赖问题。我的pom.xml也显示在这里。
Spring Boot和/或Hibernate与jdk-11之间是否存在已知的不兼容性？也许pom.xml中缺少另一个参考？
编辑：正如@nullpointer正确指出的那样，Spring 5.1支持Java11。但是，我的问题明确涉及Spring Boot。
