根据此页面，TomEE 8.0 与 Java 8 兼容：http ://tomee.apache.org/master/docs/java-compatibility.html
但是，我在使用 TomEE 和使用 java 8 的 Hibernate 设置项目时遇到了一些问题。
我从 Maven 原型 org.apache.openejb.maven:tomee-webapp-archetype 1.7.1 版创建了一个项目。我的项目 SDK 是一个简单的 JDK 1.8.0_221。
一切都很顺利。运行mvn package并mvn tomee:run启动一个运行良好的示例应用程序。
现在我转到我的 pom.xml 文件并添加 Hibernate 依赖项：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.4.14.Final</version>
</dependency>
无需对项目进行更多修改。mvn package仍然可以正常工作。但是在启动应用程序时，我得到以下信息：

根据我的研究，它看起来像一个带有 Java 8 的 ASM4 的错误：java.lang.IllegalArgumentException at org.apache.xbean.asm4.ClassReader.<init>。但是我使用的最新TomEE版本依赖于应该支持Java 8的ASM5。为什么只有在添加Hibernate依赖时才会出现问题？而且 Hibernate 5.4 似乎与 Java 8 兼容。
