JVM Options List - still being maintained post Oracle?

Is there a page anywhere with a definitive complete list of the command line options available to run a JVM? Everywhere I look I get referred to http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html which is woefully incomplete. Even the Oracle page on Java 7 just refers to the page above.

Apologies for such a basic question, but I keep coming across people suggesting useful looking options to tune the JVM that I can't find documented anywhere! e.g. CMSInitiatingOccupancyFraction

EDIT: Following the link referenced by MicTech below, and then the links from that Q, it appears that: http://stas-blogspot.blogspot.co.uk/2011/07/most-complete-list-of-xx-options-for.html is the best reference so far. Sigh.

There's an FAQ you might find useful about GC flags:

http://java.sun.com/docs/hotspot/gc1.4.2/faq.html

One thing to consider is those flags aren't "standard" so JVM implementations don't have to comply. This is why it's not listed in your link. They are implementation specific flags.
