   There are three kinds of `ClassLoader` in NetBeans Runtime 
   - `platform/lib` JARs are loaded by application classloader
   - `platform/core` JARs are loaded by enhanced NetBeans classloader, but fixed
   - `platform/modules` JARs are loaded by enhanced NetBeans classloader and fully dynamic
   
   To benefit from enhanced classloading features like [compatibility patching](http://wiki.netbeans.org/BackwardCompatibilityPatches) or [fast startup](http://wiki.apidesign.org/wiki/CacheForModularity), then it is essential to avoid placing JARs into `platform/lib` (and/or `platform/core`) folder.

   ... we are talking about  the [NetBeans Runtime Container](http://wiki.apidesign.org/wiki/NetBeans_Runtime_Container). People like @jlahoda, @tzezula and @sdedic spent a significant amount of time making sure NetBeans modules can be used in a headless mode. We are not going to ruin such efforts just because we want SVG icons.

   That would seem OK from the runtime container point of view. However expect troubles at early stages of startup - for example you couldn't use SVG to render splash screen...
   
   Good luck!
