I was listening to a podcast on SE Radio a few years ago when they were interviewing some high performance stock trader (or maybe even the NYSE engineers themselves, I don't recall) and they were talking about how they used
sun.misc.Unsafeto basically do the low level memory operations that lower level languages allow. I don't remember their reasoning on why they were using Java instead of an actual low level language but it was still fascinating.I think newer versions of the JDK have been making it difficult or impossible to access that class though.
