不能运行的OSGi bundle

Question

我试图收集束，但得到一个错误：

Caused by: java.lang.ClassNotFoundException: *** Package 'sun.misc' is not imported by bundle org.apache.camel.camel-core [12], nor is there any bundle that exports package 'sun.misc'. However, the class 'sun.misc.Unsafe' is available from the system class loader. There are two fixes: 1) Add package 'sun.misc' to the 'org.osgi.framework.system.packages.extra' property and modify bundle org.apache.camel.camel-core [12] to import this package; this causes the system bundle to export class path packages. 2) Add package 'sun.misc' to the 'org.osgi.framework.bootdelegation' property; a library or VM bug can cause classes to be loaded by the wrong class loader. The first approach is preferable for preserving modularity. ***

我使用apache camel，camel-mail和apache felix plugin

据我了解，我需要添加包装e 'sun.misc'到'org.osgi.framework.system.packages.extra'，但我不明白怎么做

帮我解决这个问题。

Answer 1

尝试在org.osgi.framework.bootdelegation属性中添加“sun。*”。
