In my case I get a VerifyError when ever I compile a release version of my custom RSLs loader which in it has a reference to spark application which cannot be used because once all the RSLs are loader including framework.swf then the class definition for sparks.components.Application can be added added. Somehow the version of gravity_shared_flex.swf from Adobe doesn't have that VerifiyError issue.
