We can also just flush (I tested both options), but I'm not really sure that it matters either way.

Suggested change
cpsExec.getOwner().getListener().getLogger().close();
cpsExec.getOwner().getListener().getLogger().flush();

Is getOwner() guaranteed to be non-null? getListener()? In principle SpotBugs should know but sometimes it seems to miss these things.

I think CpsFlowExecution.owner is guaranteed to be non-null. It's set here and here (called here).

getListener may return WorkflowRun.NULL_LISTENER, which is harmless to close, or throw an exception, but this code already handles exceptions, and I made this be the final operation in the try block so that other more important cleanup still runs even if this throws.

}
} catch (Exception ex) {
LOGGER.log(Level.WARNING, "Error persisting Pipeline execution at shutdown: "+((CpsFlowExecution) execution).owner, ex);
