Java Interactive Profiler 可以分析 osgi 捆绑包吗？解决方法是什么？

Question

you need to specify classloader to select classes to profile in JIP.But in OSGi platform each bundle has separate class loader which is decided dynamically. JIP has its own advantages.How do other profilers (yourkit,visualvm ) provide profiling for osgi bundles?

Answer 1

Try to look at http://code.google.com/p/jip-osgi/ . It is described as based on jip profiler that allows to monitor resources in OSGi application.

Answer 2

The profilers I've worked with do byte code manipulation that will inject their code in your classes. When you perform that on bundles, suddenly these bundles have a dependency on these extra classes which is resolved by putting those bundles on either the bootclasspath (the easiest, but also most implicit way) or exposing them via the system bundle (more explicit, but it requires your annotated bundles to import those classes/packages).
