Re: GUI errors on launch

Here at work there's a guy running a release candidate of our product on a MacBook. In the past 2 weeks, about 3 times now the application has failed to launch. But he launches the application about 10 times a day, so it's not a reproducible problem. He believes it has to do with launching the application immediately after rebooting his computer.

The errors, though, look very scary. They appear to be really high up in Sun's code.

You seem to have some sort of odd version confusion going...

The
Java Version: 1.4.2_09 OS Name: "Mac OS X 10.4.7"

The OS is Tiger.

Quaqua seems to think your cat is still Panther. Werner Randelshofer could verify that this should be using Tiger classes. I might be wrong and this particular class falls back to a earlier version.



java.lang.ClassNotFoundException: com.apple.mrj.swing.MacFileChooserUI

This seems weird too though, I don't find it at 1.5 or 1.4. The only place I seem to have it is in old versions of Swing 1.1.1, those versions going back to '99. I do see some references come up in Quaqua though.

I don't know off-hand what that has to do with a image download though.

Totally different error of course. Different build of the application may explain why the final error is different or it could just be different timing.


java.lang.ExceptionInInitializerError

Caused by: java.lang.ClassCastException: javax.swing.KeyStroke


It does seem to originate from the same place
[LaunchRunner Error] com.t4l.frames.Frames.main(String[]) threw an exception:
java.lang.NoClassDefFoundError
at com.t4l.image.ImageUtilities.downloadImage(ImageUtilities.java: 1084)

So maybe per the prior suggestion that is the code you need to run off the AWT Thread, or somehow serialize differently.
