-*   **Multiple Java Versions**: The PerfMark API supports Java 6, making it easy to include on 
-    older or constrained environments.  Additionally, PerfMark includes optimized backends for 
-    Java 6, Java 7, and Java 9.  Each of these backends is automatically loaded at runtime 
-    (if possible) and uses advanced JVM features for maximum speed. 
-
 *   **Chrome Trace Viewer Integration**: PerfMark can export to the Chrome Trace Event Format, 
     making it easy to view in your Web Browser.
