For example, as a post-compilation step you could massage the .class data to make the byte code either harder to read when decompiled or harder to decompile into valid Java code (or both).

Direct execution of Java byte code is possible thanks to a Java extension to the ARM processor core by ARM Ltd., Cambridge, England. Known as Jazelle, the new Java acceleration feature initially ...

Not anymore. Last year, [Michael] wrote Java Grinder, a Java byte-code compiler that compiles classes into assembly language instead of being part of a JVM.

These lighter-weight Java frameworks combine cloud-native flexibility with Java’s time-tested engineering, so you can write responsive code that’s easy to deploy anywhere.

The code snippet was provided as an answer to a StackOverflow question posted in September 2010. The code snippet printed byte counts (123,456,789 bytes) in a human-readable format, like 123.5 MB.
