Java is more secure than C and C++, ESHPESHIALLY FOR FINTECH APPS. We should port Bitcoin and Monero to Java ASAP.

I didn't say it is more secure. But your FUD was over the top.
There are ways to use the JVM especially for example with a non-Java language and careful selection of libraries that has no reason to be any less secure than C and actually can be more secure in some respects (e.g. prevent buffer overruns that C doesn't, etc).
Also if you've got a lot of high level logic buried in low level noise, you are potentially more likely to have a bug in there which could be a security hole.
It is not some C is 1000X better than JVM.
If you want to say that Java libraries and security models suck, then fine. But don't damn the JVM (virtual machine) which is stable.
Cripes then you come back and spread more FUD again.
You are a classic asshole.
OMG...hi Anonymint. Didn't realize it was you, not that I'd (out of respect) pull punches anyway.
The JVM doesn't just exist in splendid isolation. Even (falsely) assuming it's secure/stable, the JVM can't (ie shouldn't) do much of anything without its libraries and security models.
Why does pointing out the obvious advantages of 'closer-to-the-iron' low-level interfaces for security-intensive (fintech, crypto) applications make me a "classic asshole?"
Is it because you are launching your ShelbyCoin on Java, or (Goddess forbid) NXT? OMG, please tell me I'm wrong!!! I will accept (slightly) below-market consulting fees if you need help finding a better approach, just because I know your attention span and risk tolerances are extremely limited (and feel sorry for you).
