Created attachment 255209 [details]
Template to reprocude the problem

Observed on Kubuntu 14.04.2 LTS with GTK 3.10.8 and
Eclipse Java EE IDE for Web Developers.
Version: Mars Release (4.5.0)
Build id: 20150621-1200

Steps to reproduce:
1. Go to Window->Preferences->Java->Editor->Templates
2. Create a template (like the one attached) with an import declaration using the "${:import (package1, package2)}" notation.
3. Create a new class and delete _everything_ from it.
4. Type the template name, use autocompletion and select your template

Observed behaviour:
Eclipse shows a empty error window (see screenshot) and the error log show the follwing stack trace:

Expected behaviour:
As far as I can see I'm using the syntax described in the help:
http://help.eclipse.org/mars/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Fconcepts%2Fconcept-template-variables.htm
But even if I would be using wrong syntax the error message should display some useful text for the user.
