Java(TM) SE Development Kit 6 successfully installed.<\/p>\n

Product Registration is FREE and includes many benefits:
\n* Notification of new versions, patches, and updates
\n* Special offers on Oracle products, services and training
\n* Access to early releases and documentation<\/p>\n

Product and system data will be collected. If your configuration
\nsupports a browser, the JDK Product Registration form will
\nbe presented. If you do not register, none of this information
\nwill be saved. You may also register your JDK later by
\nopening the register.html file (located in the JDK installation
\ndirectory) in a browser.<\/p>\n

For more information on what data Registration collects and
\nhow it is managed and used, see:
