Yes, but you'll get these warnings the first time you use the library:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.github.jamm.MemoryMeter (file:/private/var/folders/4c/zknv2yfd7xzf8kw7m5nzdmhc0000gn/T/jamm11165273543277800685.jar) to field java.lang.String.value
WARNING: Please consider reporting this to the maintainers of org.github.jamm.MemoryMeter

We just pushed some changes to support java version up to java 17. Nevertheless, in some situation you can get that type of warnings due to how the Java Module System works with some Java versions.
