Loading class 'java.util.logging.ConsoleHandler' failed

[Hata Sashii]

Hi,
if I start my libgdx project with iPhone Simulator out of Eclipse 4.3 I got this errors/Exception:

Loading class 'java.util.logging.ConsoleHandler' failed
java.lang.ClassNotFoundException: java.util.logging.ConsoleHandler

I use Java 1.7.0_21 to comile, latest libgdx sources and robovm 0.0.5.
Also I'm using google guice in my project maybe this is the reason?
Any Ideas?
best

Hi,

RoboVM strips out unused classes in order to keep compile time and final executable size down. Unfortunately this means that classes which get loaded by using reflection (e.g. using Class.forName()) won't be linked in unless the compiler is told to do so explicitly. When you run your app from within Eclipse or from the command line using the robovm script you should see a warning when Class.forName() fails to load a class. The warning gives details on what you have to do to force the inclusion of this class.

To fix your current problem with ConsoleHandler please add

  <forceLinkClasses><pattern>java.util.logging.ConsoleHandler</pattern></forceLinkClasses>

to your robovm.xml file.

Thanks for the info! It works like a charm.

Hi!

while trying to integrate Google Guice, I was faced with the same exception (Loading class 'java.util.logging.ConsoleHandler' failed) and fixed it by using the forceLinkClasses method. However, after I was adding all indirect required classes, I get the exception below. Did you experience similar difficulties? Which dependencies are required else?

Thanks for your reply!

Cheers,

Stefan
