Would you like some Microsoft with your Java?

While installing a Java update I came across the typical bundled software option and found Sun was promoting the MSN Toolbar.  I recall previous Java updates offering the Google Toolbar and was a bit surprised to find a Microsoft product being bundled with a Java update.  Aren't Sun and Microsoft competitors?  At least their frameworks are (.Net vs. Java).

The install option was selected by default.  I took the screenshot after I unchecked it.
