Java Early-Access Download - What does FCS means?

The last Java 7 I downloaded was named

jdk-7-ea-bin-b145-windows-i586-07_jun_2011

Now it开发者_如何学Python is named

jre-7-fcs-bin-b146-windows-i586-20_jun_2011

The ea (Early Access) is replaced with fcs, but what does fcs mean?

Some companies (such as Sun Microsystems and Cisco) use FCS to describe a software version that has been shipped for revenue.
