scooter startup problem - java.lang.ClassNotFoundException: classWork failed on XXX

[stark]

Hello John,

Happy New Year! waaazzuupp..

I think i just found out a bug, i have encountered this like three times already since the last recent version, but filing it now... 

Everything's ok on my side but this time, when i just started scooter, i quickly did an alt+tab, switched to my browser and keep on spamming refresh on my page, then suddenly this.

Even if I restart the app. 

The only solution that i did was to delete the work directory of jetty AND delete on my existing class files, then let scooter again regenerate it again, then restarted scooter and it worked.

Thank You.

Happy New Year!

Not quite clear what happened to your app. Did you do "Alt+Tab" too quickly before Scooter compiles model classes? :)
