  • Array accesses are boring

    They instrumented a large set of Java benchmarks to look at the array
    accesses, over 3 billion of them in total. The majority fell into five
    simple access patterns. See the pictures on page 8 of the PDF.

    It's strange that they observed array lengths changing at the JVM
    bytecode level. That shouldn't happen.
