I am getting this message when I try to shut eclipse down thru eclipse...
I know it is because trying to communicate with the wrong port. But why?
It must have something to do with me installing a new firewall (Comodo). However, disabling it did not solve the issue.

Solution:
You are probably using Windows 7 (could be 32 bit). Uninstall Avast/AVG antivirus.
See link: http://tomcat.10.n6.nabble.com/Fwd-Re-Invalid-command-SHUTDOW-received-td2076295.html
I've switched to Comodo (antivirus + firewall) and the problem is gone.

The issue was caused by AVG LinkScanner, which should be disabled to resolve the issue.
