[GitHub] [pulsar] jerrypeng opened a new pull request #4744: Fix: predicate pushdown for Pulsar SQL NPE

jerrypeng opened a new pull request #4744: Fix: predicate pushdown for Pulsar SQL NPE
URL: https://github.com/apache/pulsar/pull/4744
 
 
   ### Motivation
   
   An NPE can be thrown when predicate pushdown for field __publish_time__ is less than any existing entry.  This is caused because OpFindNewest class in ManagedLedger returns null instead of start position if the condition fails on the first check.
