This is a known problem on Mac OS X with Java 7 and 8 prior to Java 1.8.0_45. You can work around the problem by either upgrading to the latest version of Jave (1.8.0_51) or by running Fiji using Jave 6 using the instructions at

You can avoid this Java 8 bug by using the Help>Update ImageJ command to upgrade to the latest version of ImageJ (1.50a) or by running Fiji using Java 6.

Has anyone experienced this after an update from a couple of days ago? Any hints on where we should keep looking for a possible solution?
