Request for review:
[This updated webrev is being sent to wider audience, and has been
merged with Gerard's option constraints check-in. Also factored out
-XX:+AggressiveHeap processing into it's own chapter. I mean function :-)]
This webrev adds support for handling "/deprecated/" -XX options
(options that still *do* something but are planned for removal) and
"/alias/" options (alternate names for other -XX options) by simply
adding entries to the deprecated_jvm_flags and/or aliased_jvm_flags
tables. This follows the example of the existing obsolete_jvm_flags table.
This replaces a lot of ad-hoc and occasionally wrong code in
arguments.cpp as well as supporting automatically disabling options
after a certain version.
Deprecated and alias options can be tested by adding entries to tables
in new tests:
The new tests subsume these existing tests:
jtreg (investigating errors in resource mgmt tests running on SE
embedded that seems unrelated to these changes.)
