https://bugs.openjdk.org/browse/JDK-8301958 and later changes improved Arrays.copyOf/-Range methods to improve peak performance in microbenchmarks when copying the entire array, but it's resulted in a few lurking footprint benchmark issues that come down to incurring slightly more JIT activity. As a partial remedy I propose simplifying the implementation so that no new methods are added compared to the JDK 20 baseline. This patch maintains the microbenchmark speed-up from JDK-8301958 while reducing JIT compilations in startup/footprint benchmarks.
