InstantiationException problems
Feb 8th, 2006, 12:33am  
Hi,

I've got a Processing sketch called `Trees 3`. You can see the current version here: http://www.3tree.info

I'm currently writing a new version. The first thing I'm trying is a splash screen.

You can see the new code so far: http://pastebin.com/544131 - main file
http://pastebin.com/544138 - thread class

When I run this code, I get a java.lang.InstantiationException: SplashThread

I looked up the JDK API, and an InstantiationException should be triggered by trying to instantiate an interface or an abstract class. As you can see, SplashThread is neither.

Could anyone help me out in trying to figure out what the problem is?

Thanks

I'm not sure if this is documented or a mac thing, but when I rename SplashThread to SplashThread.java, it works fine. The really interesting (disturbing) thing is that the suffix doesn't need to be on the file, after I specify the.java once in processing. I can then remove .java from the file, and it will still work. I can even, using tabs>rename change SplashThread.java to SplashThread and it will still work and the tab itself will still maintain the .java

renaming to SplashThread.java will tell the preproc to lay off and not integrate that code into the main PApplet class. sounds like there's code in SplashThread that's not happy being an internal class.

as for the renaming not getting rid of the .java, that's a bug, if you care to file it in the bugs db.
