【问题描述】：

我正在将 Java 8 项目转换为 Java 11，作为转换的一部分，我进行了一系列不同的代码更改和升级（最值得注意的是从 4.​​x 升级到 Hibernate 5.3.18.FINAL。 X）。我已经让整个大型项目在 Java 11 中成功编译。但是，当我使用 Karaf 启动项目时，我遇到了一个持续的 OSGi 错误，这让我发疯了。

在你问之前，我已经将匹配的 bytebuddy 和 javassist 的每一个组合都放在了 pom 文件中（匹配 5.3.18.FINAL 所需的版本），但这并不能解决问题。请注意，我的项目在 Maven 中成功构建，但是当我使用 karaf 启动它时根本找不到 HibernateProxy。降级到 Java 8 不是一种选择 - 这需要在 Java 11 中运行。

更多技术细节： 使用 Spring Boot 使用蓝图 Hibernate.xml 更新为 persistence_2_1.xsd

<jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=abc)</jta-data-source>

数据库是h2

【参考方案1】：

虽然这不是一个完美的解决方案，但我能够暂时解决这个问题的方法是在主类路径中强制使用 hibernate-core jar。我确定主要问题是 hibernate-core 不在正确的位置，但我不清楚如何。我对 pom 进行了很多操作并为 maven-bundle-plugin 添加了异常，但这不起作用 - 只是将 hibernate-core 放在主类路径中。
