CAUSE

During the Weblogic server installation process we apply multiple Weblogic patches and those need to be cleaned and activated.

SOLUTION

After applying Weblogic patches using smart update, we have to activate those patches and that we can do via below command.

Go to workshop folder in bea home directory(Oracle Weblogic installation directory) and then workshop_10.3 folder and run the command as below.

workshop.exe -clean -initialize

Hope this helps in resolving famous internal compiler error in you weblogic workshop or eclipse, Please leave your feedback or query.
