解决Spring OSGi 中no declaration can be found for element 'oxm:jaxb2-marshaller'

又是一个老问题，没过多久差点忘记了。还是记录下来吧！

一个新建的bundle启动时出现一下错误：

Error

这也算是Spring OSGi中一个诡异的问题。没有查阅过具体的文档，但调试了几次发现，如果dependency的bundle有schema定义，则这个bundle必须加到Eclipse/configuration/config.ini 显示的Start。上面的问题就是因为没有将oxm的bundle加入到config.ini中start。
