For those of us using Macs we seem to relatively often run up against certificates (such as login-dev or olt-dev) not being in our cacerts certificate store even after we are sure that we’ve added them.
A comment I found on another site (http://mediakey.dk/~cc/java-default-keystore-password-cacerts/) suggests why.
It would appear that Apple updates (and I suspect simply replaces) the cacerts file during some of their software updates. This will infact completely reset your cacerts store.
Also note that the other article also notes that apple have changed the default password from ‘changeit’ to ‘changeme’
