Review comment:
Instead of returning false on errors, you could throw Exception, and have
that carry the context of the error (ledger id, entry id etc). This would
simplify the loops in the test itself, as you wouldn't have to do anything to
get the ledger and entry id, as it'd already be in the exception message. In
fact, the loop could be reduced to
```executor.invokeAll(writeTasks, 6, TimeUnit.SECONDS).forEach(f ->
f.join())```
