A simple fix probably warrants an immediate backport where desired. In the case of complex fixes, sufficient soak time can help avoid duplicate work for an engineer in JDK 9 and JDK 8u if regressions were seen.

We are also often able to rely on area leads to provide advice on the mailing list when a change should spend an extra round or few to soak.
