Welcome to BlackBerry Support Forums
Which version of BlackBerry world is Installed in your device , can you try this KB and see if that the cause :
KB31240 : "Uncaught exception: java lang error" is displayed when upgrading from BlackBerry App World 1.0 and 1.1.
If that not the cause then you have to remember if you recently installed any application, if you have then uninstall that application which you think might be responsible and after which this error appeared .Try it and let us know.
