[GitHub] [pulsar] rdhabalia opened a new pull request #4090: [pulsar-function] Fix NPE and log error when java-instance jar path not set

rdhabalia opened a new pull request #4090: [pulsar-function] Fix NPE and log error when java-instance jar path not set
URL: https://github.com/apache/pulsar/pull/4090
 
 
   ### Motivation
   
   When java-instance jar path is not set, function internally throws NPE without logging any root-cause.
   
   ```
   java.lang.NullPointerException: null
           at org.apache.pulsar.common.nar.NarClassLoader.<init>(NarClassLoader.java:175)
