Hi Mandy, Peter,

thanks for the review.

I wanted the patch to be small and only in PlatformLogger class without API
change to be easily backported to jdk7u.
Do you think this bug is JDK8 only ?


I submitted another patch concerning missing
PlatformLogger.isLoggable(level) in the JDK (java.net, java.awt mainly) but
it is not widely used as I thought first.

see http://mail.openjdk.java.net/pipermail/awt-dev/2013-March/004459.html

Maybe in the future, other projects or JDK parts will use it if it is no
more a performance bottleneck.
