Currently, when JWS 1.0.1_02 is integrated into Merlin, the Installshield installer will NOT overwrite 1.0.1x with 1.0.1_02 at install time. This behavior was a workaround for bug 4488579, which caused the JWS cache to be deleted when it installed over an existing JWS.

Since we have fixed 4488579 in 1.0.1_02, and more importantly, since there is a needed security fix (4522528) in 1.0.1_02, we should now change the behavior of the Merlin installer: the bundled 1.0.1_02 should now overwrite an existing 1.0.1x.
