Hi again Jakob,

 After a brief chat with Curtis Rueden[1], it looks like the problem is
that Java 6 is required to be installed even though Fiji can be launched in
a Java 8 JVM. It works on developer machines like mine because I have Java
6, 7 and 8 installed for testing.

 If you have a Yosemite mac WITHOUT Java 6 installed, could you try
replacing the jars/imagej-launcher-xxx.jar in your Fiji with this version:
http://jenkins.imagej.net/job/ImageJ-launcher/label=MacOSX/1205/artifact/target/imagej-launcher-3.3.0.jar

 This release of the ImageJ-launcher has fixes that are supposed to remove
the need for Java 6, but is not a part of Fiji yet because it's not well
tested. If you can confirm that it fixes the problem for you that would be
fantastic.

Best,
Mark
