<div class="jive-rendered-content"><p>Hi Kabir,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I just implemented something like this for the OSGi performance benchmarks. Here's a quick description of the bundle dependency topology that it creates:</p><p> 5 (Versioned) Common Bundles<br/>   - Exports org.jboss.osgi.test.common;version=x<br/> 5 Numbered (but not versioned) Util Bundles<br/>   - Imports org.jboss.osgi.test.common<br/>   - Exports org.jboss.osgi.test.util[x];uses="org.jboss.osgi.test.common"<br/> 5 Versioned Interfaces Bundles<br/>   - Exports org.jboss.osgi.test.versioned;version=x<br/> 5 Versioned Impl Bundles<br/>   - Imports org.jboss.osgi.test.common;version=[x,x]<br/>   - Imports org.jboss.osgi.test.versioned;version=[x,x]<br/>   - Imports org.jboss.osgi.test.util[x]<br/>   - Exports org.jboss.osgi.test.versioned.impl;version=x;uses=org.jboss.osgi.test.util[x]<br/> a large number of test bundles (number configurable)<br/>   - Imports org.jboss.osgi.test.common;version=[x,x]<br/>   - Imports org.jboss.osgi.test.versioned;version=[x,x]<br/>   - Imports org.jboss.osgi.test.versioned.impl;version=[x,x]</p><p>Where x is a number [1..5].</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Each test bundle loads a class of each of its 3 dependency packages in its activator. This also triggers an indirect load on the Util[x] class.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>It's available on master in jbosgi on github: <a class="jive-link-external-small" href="http://github.com/jbosgi/jbosgi/blob/master/testsuite/performance/src/test/java/org/jboss/osgi/test/performance/bundle/BundleInstallAndStartBenchmark.java">BundleInstallAndStartBenchmark.java</a></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>You might be able to reuse some of this...</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>David</p></div>
