PROSAGA码农传奇-SF服务编织-未调用Apache Felix OSGi框架的WeavingHook.weave（）方法

我使用fabric8-karaf-1.1.0.CR5，其中包括：
<pre><code>.../system/org/apache/felix/org.apache.felix.framework/4.0.3.redhat-610379/org.apache.felix.framework-4.0.3.redhat-610379.jar
</code></pre>… / org.apache.felix.framework-4.0.0 / doc / changelog.txt包含：
<pre><code> ** New Feature
 * [FELIX-2959] - [Framework] Implement OSGi R4.3 class loader byte-code weaving hook
</code></pre>我添加到…/etc/startup.properties： <code>
igb/igb.osgi.weaving/1.0.0/igb.osgi.weaving-1.0.0.jar=1
</code> 我的捆绑包激活器：
<pre><code>package igb.osgi.weaving;

import java.util.Hashtable;

import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import org.osgi.framework.hooks.weaving.WeavingHook;

public class Activator implements BundleActivator {
 public void start( BundleContext bc ) throws Exception {
 System.out.println( "Starting " + Activator.class.getName() );
 // this doesn't work
 //bc.registerService( Weaver.class, new Weaver(), new Hashtable<String, Object>() );
 // this is the proper way, see BJ Hargrave's accepted answer below
 bc.registerService( WeavingHook.class, new Weaver(), new Hashtable<String, Object>() );
 }
 public void stop( BundleContext bc ) throws Exception {
 System.out.println( "Stopping " + Activator.class.getName() );
 }
 } // Activator
</code></pre>我的编织钩：
<pre><code>package igb.osgi.weaving;

import org.osgi.framework.hooks.weaving.WeavingHook;
import org.osgi.framework.hooks.weaving.WovenClass;

public class Weaver implements WeavingHook {
    synchronized public void weave( WovenClass wc ) {
        System.out.println( "Weaving " + wc.getClassName() );
        }
} // Weaver

</code></pre>但是我的Weaver对象没有输出“ Weaving …”。我的捆绑包处于活动状态：
<pre><code>Fabric8:karaf@root> list|grep IGB
[ 1] [Active ] [ ] [ 1] IGB OSGi Weaving (1.0.0)
</code></pre>我的Weaver服务得到认可：
<pre><code>Fabric8:karaf@root> ls 1
You are about to access system bundle 1. Do you wish to continue (yes/no): yes

IGB OSGi Weaving (1) provides:
------------------------------
objectClass = igb.osgi.weaving.Weaver
service.id = 3
</code></pre>但是似乎没有使用它：
<pre><code>Fabric8:karaf@root> ls -u|grep -i igb
Fabric8:karaf@root>

</code></pre>在OSGi服务平台第四版4.3版核心规格，56.3编织服务社，351页记载：该框架获取Weaving Hook服务，并为必须加载的每个类调用其weave方法。我将其解释为无事可做。我哪里错了？PS：Activator的代码适合于反映已接受的答案。
