Complete list of JVM options [duplicate]

Question

This question already has answers here:

Print All JVM Flags (2 answers)

Closed 9 months ago.

Besides official documentation I have found only this post. But it is quite old and incomplete (only -XX options available). For example, I couldn't find -XX:AutoBoxCacheMax option in none of them.

Where the complete list can be found if it exists?

Answer 1

You can use

java -XX:+UnlockDiagnosticVMOptions -XX:+PrintFlagsFinal -version

to print all options and their defaults. If you have a debug build you can use this command to print comments for the various options as well:

java -XX:+UnlockDiagnosticVMOptions -XX:+UnlockExperimentalVMOptions -XX:+PrintFlagsFinal -XX:+PrintFlagsWithComments -version

PS: There are descriptions for most of them in this blog post: http://stas-blogspot.blogspot.bg/2011/07/most-complete-list-of-xx-options-for.html
