Shutdown command with Apache Tomcat and Eclipse 3.4.2

By shutting down Apache Tomcat 5.5. within the servers by using Eclipse 3.4.2 I sometimes get the next error

StandardServer.await: Invalid command '' received or
StandardServer.await: Invalid command ''SHUTDOW" received

The command should be SHUTDOWN.

This is happening sometimes and not always when shutting down Tomcat so this makes it very strange for me.

I have adjusted the server.xml file so that could be problem, but with the normal server.xml file I get the same problem.

The line in the server.xml file is <Server port="8005" shutdown="SHUTDOWN">

Possible solutions

Make Eclipse give the correct command always.
Let Tomcat make the shutdown without the command or a list of commands.

Do you know how to accomplish this or is there an other solution.

Thanks in advance,
