I gave it a bit more thoughts, and am inclining to agree that replying on env. variables is indeed fragile. so I've decided to go w/ a new WB method --http://cr.openjdk.java.net/~iignatyev//8216180/webrev.01/index.html <http://cr.openjdk.java.net/~iignatyev//8216180/webrev.01/index.html>
(testing is in-progress)

>>> the test disables some intrinsics, and if it's run w/ AOT'ed java.base there these intrinsics are enabled (which is the most common, if not the only, case) we get crash. the fix introduces new @requires value -- vm.aot.modules which contains comma-separated list of AOT'ed modules and use it to skip this test if java.base is one of them.
