> Under moderate concurrency (25threads) and frequent use of new java.net.URL(string) a bottleneck was seen with yourkit.  In one test involving HTML page generation new URL(url) was seen to take 20% of time (via yourkit).
> This was tracked to org.apache.felix.framework.URLHandlersStreamHandlerProxy.getStreamHandlerService() URLHandlersStreamHandlerProxy.java which accounted for 99% of the time used by new URL(url).
