Just wanted to make sure everyone saw this (, since it will
likely have a large impact on how your virtualize your Java workloads in
the future.

Essentially OSv is designed to run one application only, in kernel/real
mode. With virtualization, that's an OK thing, because the worst that can
happen is the application destroys itself. But since the JVM does byte code
verification, the risk is really really low. Think of this as a very modern
and elegant real mode DOS... and imagine if the JVM could access the page
table directly. this could have huge implications for garbage collection as
mentioned on their site.

Anyway, they're considering writing enhanced versions of the JVM, and even
specific Java applications like Tomcat to take advantage of OSv features.
It'd be super cool if TomEE was also a part of that! The tech is still in
in Alpha stages, but this is definitely something to watch.
