Register hk2-locator and javassist as bundles on your OSGi framework.
将 hk2-locator 和 javassist 注册为 OSGi 框架上的包。
Jersey uses hk2-locator to find services on OSGi.
Jersey 使用 hk2-locator 在 OSGi 上查找服务。

I had this same issue and I could finally solve it by starting my bundle which uses Jersey to publish an endpoint at level 2 in the Felix Framework (OSGi-5.4). I am not sure why, but seems like the HK2-Locator dependencies:
我遇到了同样的问题，我终于可以通过启动我的包来解决它，该包使用 Jersey 在 Felix 框架 (OSGi-5.4) 的第 2 级发布端点。我不知道为什么，但似乎是 HK2-Locator 依赖项：
- hk2-api-2.4.0-b10.jar -> Level 1
- hk2-locator-2.4.0-b10.jar -> Level 1
- hk2-utils-2.4.0-b10.jar -> Level 1
- org.apache.servicemix.bundles.javax-inject-1_2.jar -> Level 1
- jersey-guava-2.22.1.jar -> Level 1
- hk2-api-2.4.0-b10.jar -> 级别 1
- hk2-locator-2.4.0-b10.jar -> 级别 1
- hk2-utils-2.4.0-b10.jar -> 级别 1
- org.apache.servicemix.bundles.javax-inject-1_2.jar -> 级别 1
- jersey-guava-2.22.1.jar -> 级别 1
need to start first before the bundle who uses them:
需要在使用它们的捆绑包之前首先启动：
- your-bundle-1.0.0.jar -> Level 2
- your-bundle-1.0.0.jar -> 级别 2
Once you set your bundle to start on this new level then make sure to execute frameworklevel 2in Felix console to start the bundles under that level. Restart the framework and it will work.
一旦您将捆绑包设置为在此新级别上启动，请确保frameworklevel 2在 Felix 控制台中执行以启动该级别下的捆绑包。重新启动框架，它将起作用。
