How to work with very long text elements in comboboxes

So, I have text that is rather long than some of the components that they occupy. I came up with reasonable solutions for most problems, but I don’t know what to do with very long text elements in combined blocks. If the user cannot see the text, he cannot make the right decision - especially if the first part of the text matches. See SSCCE below.

I used JScrollpane to solve the long text problem in the JTextfield field, and I used the tooltip to resolve the long text in the JXhyperlink field. In addition, I have a tooltip for the combo box that can display a long item AFTER it has been selected, but ideally I would like to give this opportunity to the user before he makes his choice. This code sample was compiled using Netbeans graphic designer (great for RAD purposes), and the layout is GroupLayout, which uses the GUI designer.
