As part of AOT/Leyden testing we want to run jtreg tests with AOT cache.
Ideally this cache should contain the assets from the application/test train run.
To accomplish this all jtreg tests need to be run twice.
This require jtreg harness modification as well.
For simplicity reasons we will create AOT cache which will contains only jdk classes (no test/application specific classes)
and then run jtreg tests with this AOT cache. This approach doesn't require jtreg harness changes.
