Exception in Code Generation

[Niclas Hedhman]

Starting today, on existing .ioc file, CubeMX "suddenly" complaining that project generation had a problem. "Suddenly" refers to that I have generated code incrementally many times the last few days on the same project, and today I added "FatFS" which was the first time I got it. So I disabled FatFS, but the problem persists.

Starting CubeMX from command-line I got to the following Exception;

 What is the MailBox? Using RMI, which is so outdated it is not funny? I was involved in its death, via JSR-76 and JSR-78 in 2001. Since those weren't approved, RMI was too great of a security risk. I urge you to get rid of it
