I think thats already enabled. I think {color:red}sun.*{color} below should
achieve that?

> Key: FELIX-5665
> URL: https://issues.apache.org/jira/browse/FELIX-5665
> Project: Felix
> Issue Type: Bug
> Affects Versions: framework-5.6.4
> Reporter: AnilKumar Attuluri
> Attachments: IMG_1.jpg, IMG_2.jpg
>
>
> We have been running some performance tests to prepare our OSGi bundle
> (*running in Apache Karaf*) for production.
> Just to give some background about our OSGi bundle, we converted an existing
> Spring application into an OSGi bundle with all the current dependencies
> packaged into the bundle as an uber artifact.
> When we run >= 500 TPS (each of these calls results in a http call made via a
> library) we run into this high CPU usage spikes reaching up to 100% CPU.
> Please see the image attached, the spikes in the image are 100% CPU usage
> while the average is about 40%. Also see the CPU sampler image which points
> to
> *org.apache.felix.framework.BundleWiringImpl.findClassOrResourceByDelegation*
> Is there an existing bug/documentation that already captures this?
> We don't see this behavior when we run the same app in standalone JVM.
