#7919 was forced to be closed.
I've opened a new pr to address rebase issue.
Pulsar enable throttler to controll the speed of consuming data. But sometimes ctx will be closed while throttler is running in a independent thread. We should check ctx null point before setting auto read.
NPE will be thrown if throttler is enabled and ctx is closed. It would be more graceful if we check null before enabling auto read
