Hi all,

When I ran HeapStats Analyzer [1] on JDK 9 EA b124, I encountered ClassNotFoundException as below:
java.lang.ClassNotFoundException: com.sun.deploy.uitoolkit.impl.fx.HostServicesFactory
         at jdk.internal.loader.BuiltinClassLoader.loadClass(java.base at 9-ea/
         at java.lang.ClassLoader.loadClass(java.base at 9-ea/
         at java.lang.Class.forName0(java.base at 9-ea/Native Method)
         at java.lang.Class.forName(java.base at 9-ea/
         at com.sun.javafx.application.HostServicesDelegate.lambda$getInstance$0( at 9-ea/

This message does not appear on JDK 8u92.
I think this message is printed at [2].

I think this exception message do not need to be printed.
At least, it is debug level.

Does someone work for it?
If not so, I want to contribute patch.
