Is the JVM Options List still being maintained anywhere? It seems to have disappeared from Oracle's website, but luckily the Wayback Machine has a copy.
Use java -XX:+PrintFlagsFinal
to print available -XX options.
More diagnostic and experimental options can be added to list with following options:
-XX:+UnlockDiagnosticVMOptions
-XX:+UnlockExperimentalVMOptions
(for Sun)
-XX:+UnlockInternalVMOptions
(for JRockit)
NOTE: Current version of javac
docs for Java 8 contains list of most -XX
options: https://docs.oracle.com/javase/8/docs/technotes/tools/windows/java.html
