> `SQLExecution.withNewExecutionId` dereferences sc.dagScheduler inside its 
> finally block. SparkContext.stop() sets _dagScheduler to null before it stops 
> the listener bus, so a query that finishes while the context is being torn 
> down reaches that line with a null receiver and throws a 
> `NullPointerException`.
> Because the NPE is thrown from a finally, it replaces the query's original 
> exception rather than being suppressed, and it skips every remaining cleanup 
> step in the block.
