Even before 0x, a there was definitely a genuine performance need that drove a lot of stuff from Java to C++.  A lot of people I know would write <i>Javaish</i> code with Boost.<p>A lot of the stuff that makes Java great for building high level systems quickly is still kind of missing from formal C++ though (IoC, JMX, etc...), and it would have been nice to see some of the internal stuff get open sourced.<p>I wonder if people are starting to avoid Java because of Oracle (e.g. vs Google).
