For less difficult Lower and paste operations, it’s also probable to make use of the method identify format produced by helpful hints the -XX:+PrintCompilation and -XX:+LogCompilation selections:
When functioning many JVM procedures, AppCDS lowers the runtime footprint with memory sharing for study-only metadata.
