Is there any console output? (How to get the output: Build and run Processing with ant, see the GitHub wiki. The output will be shown in the console window you started ant). Are you using the with Processing shipped java version?

I use the Processing shipped with java, in the Resource Monitor the CPU gets to 11% then goes down while the Processing Logo Fades.
I just tried tried lunching processing with the command line, and there was no output. I attach the memory process of java.exe and javaw.exe

Did you ran the debug function? (processing.exe --l4j-debug). Is there any not-zero exit code? (Perhaps 259??)

I get nothing in the debug command line, just the processing logo

check for a launch4j.log file in your processing folder. There l4j stores the debug output.

ahh ok sorry it this

1. Does processing prints any console output? (Try .\java\bin\java -cp lib/pde.jar;core/library/core.jar;lib/jna.jar;lib/antlr.jar;lib/ant.jar;lib/ant-launcher.jar;lib/org-netbeans-swing-outline.jar;lib/com.ibm.icu_4.4.2.v20110823.jar;lib/jdi.jar;lib/jdimodel.jar;lib/org.eclipse.osgi_3.8.1.v20120830-144521.jar processing.app.Base from the command-line).
2. See processing doesn't open w/ no error #1899 (thats the same l4j log). Try redownloading processing. Perhaps theres something wrong with your build. (Or try building yourself...)

I tried that in the console, it seems there is a problem with javascriptmode

Try restarting after removing every modes/tools.

as I know javascriptMode was remove from processing 2.0, so maybe there is still a link to that mode in the code from previous versions(betas).

move (or rename) the "USER/AppData/Roaming/Processing/" folder and rename the sketchbook to something else and then start processing.

Yeah that totally work, thanks!
So after running processing I pointed out where my sketchbook directory is, and restarted Processing. So it fail again. I went to my sketchbook directory and deleted the folder mode, the folder only has one mode and its not javascript. After doing that processing 2.0 runs again smoothly.
I think processing tries to find the javacriptMode in the sketchbook and doing so it fails to run.
