I am still quite new to Vaadin, and even to Java in WEB environment (application servers, servlet containers or whatever the Tomcat is.), but as new as with Vaadin it self.
I was playing with Addressbook tutorial, and so I have made some trivial changes to the code. But when I had tried to run this on my laptop (first with tomcat.) it didn’t work so well. The original Addressbook example will run on tomcat without issues. Is it possible that 4 GB of RAM, shared with operating system (Ubuntu) and Java are not enough for Vaadin and Tomcat (tried 8 and 7) to run so trivial application?
It will run with Jetty (on laptop), and also on Tomcat, without issues, on my desktop worksation, which has 16 GB or RAM.
Software configuration is indentical between laptop and desktop machine. Java 8, Ubuntu 14.04 64 Bit, Tomcat 8.0.3 and 7.0.52, Netbeans 8…
For the case some would like to check error messages I got displayed in Netbeans, and changes I made to code here are the links to the files (If someone wants I can post the code here also.):

Edit:
When I try to add secon link by clicking the link icon from the toolbar, I just get the option to edit the first link… Is this a feature or a bug : )?
