            I would like to create a custom relation. However, there are no custom relation templates. (Essentially, all I really want is to be able to have a multi-line qualifier (q1,q2) on the relation. I was thinking of using the backslash that works so well in other elements. So, you could just implement that and I would be happy.) Thoughts?

            This is the favourite UML tool in our office. Sdedit (http://sdedit.sourceforge.net/) is a nice addition for sequence diagrams.

            Thanks for the great software.

            I have been using it for a while now and find it much better that any other tool I have tried before.

            Lovely tool for its extensibility...

            A suggestion: if custom elements could extend existing elements, customisation would be very much easier. I want to extend the 'Relation' element to add a state-machine 'interrupt' transition which is the same as the normal arrow but looks like a lightning-bolt to represent a departure from normal flow.

            Immediately fails with 'Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file'

            Admittedly this could be Java's fault.
