java.util.logging is currently handled by the Serviceability Team. Adding that alias to this e-mail thread...

Moving the mouse pointer over a java.awt.Window using JRE7 consumes aprox. twice the CPU time as with JRE6 when logging is used (when a call to java.util.logging.getLogger(String)---even without using the returned Logger--- has been done). Keyboard key event processing suffers the same performance penalty. For steps to reproduce this problem please look at: http://www.java.net/forum/topic/performance/general-performance-discussion/jre7s-javaawt-performance-degradation-caused-javautillogging-linux . The performance degradation seems to be "enabled" by the call of sun.util.logging.PlatformLogger.redirectPlatformLoggers() done inside java.util.LogManager.readPrimorialConfiguration() on JRE7. Call chain: Logger.getLogger()->LogManager.getLogManager()-> LogManager.readPrimordialConfiguration()->sun.util.logging.PlatformLogger.redirectPlatformLoggers(). This call is not made on JRE6. If this problem is not easy to solve then I guess is better to remove this call from JRE7's readPrimordialConfiguration as it does more harm than good. Please let me know if there is a better place to report this problem. A couple of weeks ago I "opened" a bug report on bugs.sun.com but I received no response at all. Cheers, Nicolas
