Description Daniel R Somerfield CLA 2005-08-04 17:02:59 EDT 
1. With APT globally disabled, open annotation processing preference.
2. Select "Configure project-specfic settings" and Enable project-specific
settings for your project.
3. Without changing anything (annotation processing should already be off) Ok
the change.

An error occurs:

Comment 1 Jess Garms CLA 2005-08-04 17:50:15 EDT 
Need to check getKind() of compilation result in ReconcileWorkingCopyOperation
before casting.
Comment 2 Jess Garms CLA 2005-08-04 18:41:14 EDT 
Added check before casting.
