This may cause the dump() to have a probability of being skipped.
What about waiting for the isValid to be true for a certain time?

Not very friendly, potentially a long time, like node just starting up as before, cost 15+ s.

As I see, isValid is used for sync dump() with flush(), isAlive is used for recovery().
isValid changes from false to true may not take a long time, just waiting for 1 or 2 seconds is enough?

There's really no need to think about flush() for kill -15, flush() will always take precedence in here https://github.com/tronprotocol/java-tron/blob/release_v4.7.3/framework/src/main/java/org/tron/common/application/ApplicationImpl.java#L73
