JDK installs FX SDK now(There is a note "The JavaFX SDK is now included as part of the JDK"). "Development Tools" Feature Description("Custom Setup" dialog):
"Java SE Development Kit 7 Update 6, including private JRE and JavaFX runtime. This will require 300MB on your hard drive". There is no information about FX SDK.
Should be something like "Java SE Development Kit 7 Update 6, including FX SDK, private JRE and JavaFX runtime..."
