Java update tool jusched.exe occupying HTTP port 80

Today when I started my Tomcat server it was not starting, saying that port 80 was occupied. Then I downloaded this useful tool TCP View - http://technet.microsoft.com/en-us/sysinternals/bb897437.aspx

which showed me that jusched.exe was occupying port 80, then I killed the process, and then started the Tomcat server. Strange why java update tool is occupying port 80
