Subject [jira] [Commented] (CXF-3867) Fix for CXF-1816 causes startup performance regression

It looks like the approach of using a META-INF/cxf/org.apache.cxf.JDKBugHacks.defaultUsesCaches
file to configure this feature requires the resource to be in the system classloader (because

The problem stems from changing the default value for URL connection caching to false which
really slows down classloader performance. Perhaps CXF could make this workaround configurable
like Tomcat does with the urlCacheProtection setting?
