I have very little experience with java myself, so am definatley an expert on the subject.
I'm sure that java can be secure, and that there are a large number of well tested in the field java libs that can be presumed to be implimented securely, which is often a better scenario than custom implimentations by devs who are somewhat out of thier league, or just wanting to get past the boring areas in focus on the more interesting (to them) parts of the project.
Was kinda just having a troll at the devs, mostly cos, in my limited knowledge (making me an expert!) of this project puts me in moral oposition to what i perceive as the main goals driving it.
