I filed JDK-8351894: [premain] more ways to trigger AOT dumps
My purpose is to expedite our creation of a mid-application End Training Run hook.
The sooner we create the hook the sooner we can shake out more bugs
like the one fixed here.
A very simple hook will do; I propose java.lang.System::endTrainingRun().
