Coin based on Java... I can't believe my eyes, coin developed with most insecure and inefficient bloated language full with frameworks for lazy/incapable devs. This thing does not sound right and will have serious problems.
Java itself is not insecure today. And efficiency is not a big problem for PoS currency, good enough for quick start. Things can be much worse if devs used PHP or Perl 
Anyway, I hope we'll get better client in Jan/Feb next year.
Btw, did you know that there are a lot of hi-load financial software written in Java?
