That's not a follow up as in reply, just someone saying they have the same problem someone else had 19 years ago. While that API has changed a bit(I haven't heard of a pop3.jar), if you only specifically need Gmail I just use their API (https://developers.google.com/api-client-library/java/apis/gmail/v1).

Late reply (been away - just returned): I had that problem recently when
compiling code under Java 8 that was written and last compiled under Java
6 and that used the mstor provider to access mail held as multiple
messages in each file. The cure was simple: download the current mstor
source, compile it and use it. The problem seemed to be a change in the
the security managed to made it incompatible with old mstor jarfiles, so
presumably the same problem can happen with any old mail provider code.
