Mac Mountain Lion has the same password now it uses Oracle

which means that cacerts keystore isn t password protected   That s a false assumption  If you read more carefully  you ll find that the listing was provided without verifying the integrity of the keystore because you didn t provide the password  The listing doesn t require a password  but your keystore definitely has a password  as indicated by      In order to verify its integrity  you must provide your keystore password    Java s default cacerts password is  changeit   unless you re on a Mac  where it s  changeme  up to a certain point  Apparently as of Mountain Lion  based on comments and another answer here   the password for Mac is now also  changeit   probably because Oracle is now handling distribution for the Mac JVM as well
