I must say pointing to slides that comment on flaws mostly corrected in Java 1.2 with the strictfp keyword. And comments on concerns otherwise only applicable to people who actually do numerical analysis on their code. i.e. all those for who -ffast-math is most likely not acceptable. For those people who actually care about numerical analysis and stability java 8 (finally) gives them a way to do overflow safe code. The second is that the a decent JVM i.e. not Dalvik do generate vector instruction streams. I actually think that java code in the next 4 years will start to be much faster than equivalent C code, due to HSAIL and Graals potential to involve GPUs and specialized floating point hardware in an otherwise normal program.
