Caused by: java.lang.NullPointerException
at sun.awt.X11FontManager.getDefaultPlatformFont(X11FontManager.java:779)
at sun.font.SunFontManager$2.run(SunFontManager.java:432)
Cause
OpenJDK is used.
Resolution
Use Oracle JDK instead.According to the List of Supported Platforms: "We highly recommend that you use the Oracle JVM (or use the default Mac OS X JVM), as other implementations have not been tested."
As you switch jdk, you will also need to move (for backup purposes) the entire folder FISHEYE_INST/cache/plugins before starting Fisheye with the new JDK.
