我在karaf下运行pax考试时遇到问题。 在安装捆绑包
期间2015-05-20 14:16:42,644 | DEBUG | FelixStartLevel | BundleManager | 1 - org.apache.karaf.features.core - 3.0.0 | Checking file:/tmp/ops4j-store-anonymous-568188393605841387/tinybundles_c3beb06a2df3da75e08a1ae1a44c832cfbd034c0.bin
它在
中挂了一段时间org.apache.karaf.features.internal.BundleManager#waitForUrlHandler
寻找
(&(objectClass=org.osgi.service.url.URLStreamHandlerService)(url.handler.protocol=file))
这里是线程转储：

我没有找到任何提供该服务的捆绑包=＆gt;因此，每次安装tinybundle的文件夹时，我的测试都会挂起30秒。
我已经从目标文件夹手动启动了一个paxexam的karaf，我运行了service：list来查看哪些bundle可以提供URLStreamHandlerService服务但是没有任何url.handler.protocol =文件
service.id = 2

System Bundle (0)
Used by:
Apache Felix File Install (17)
Apache Aries JMX Core (225)

所以问题是：我怎样才能避免等待超时。我们真的需要URLStreamHandlerService服务，如果是，我该如何提供呢？
