@caoman Thanks for reviewing!

When hermetic is supported, I think we will want to add new tests to explicitly 
exercise packaging a single executable image including the runtime and run 
using the single image. Those would be dedicated tests, instead of testing 
all/most jtreg tests in hermetic mode. `isHermetic` could be useful when we add 
such tests.
