Does it matter if I run preverified class files through DashO?
It is OK to run preverified classes through DashO Embedded Edition, but it will strip the extra information added by the preverifier from all classes that it outputs. This means that you must preverify your output classes after running DashO on them. The reason for this requirement is that DashO may invalidate the information inserted by the preverifier when it transforms your class files.
