Hibernate OSGi和JNI的类加载问题

我有一个OSGi应用程序，它可以从命令行启动并正常运行。然而，在生产环境中，这个应用程序必须从用C编写的小程序启动。这个程序检查许可证，做其他事情，并在我的应用程序中使用JNI启动java虚拟机。通过这种方式，我从log4j和hibernate中得到了奇怪的错误，我启用了-verbose:class JVM标志：

[Loaded org.apache.log4j.Appender from reference:file:/opt/dc/lib/log4j-1.2.15.jar]

为什么这些类要加载两次？为什么有些是从Felix加载的，有些是从Java类加载器加载的？我怀疑一些本机代码在OSGi应用程序启动之前调用java，例如日志记录，然后加载的类以某种方式被重用，导致ClassCastException-我如何证明或反驳这一点？

问题出在程序启动器内部。它将所有包添加到JVM的类路径中，尽管只需要Felix jar
