Exceptions thrown in Elasticsearch initialization thread are ignored, so in case of any error, Elasticsearch connector is started with client = null and lots of NPE are thrown during startup.

Correct behavior should be: catch all startup exceptions and in case of error, don't start Elasticsearch connector in a inconsistent state

Root cause
Caused by LPS-85003, in that LPS following commit added the new "Elastic search initialization thread":

• https://github.com/liferay/liferay-portal/commit/243dd9dc6bcb85558a58fe3fd261e931d81ecf05

Steps to reproduce

1. Setup a Liferay installation.
2. Start it and verify that [LIFERAY_HOME]/data/elasticsearch6 folder was created and no error is thrown during startup
3. Stop Liferay
4. Go to [LIFERAY_HOME]/data and execute following commands in order to force an Elasticsearch initialization error

   1. mv elasticsearch6 elasticsearch6_old

   2. touch elasticsearch6

5. Start Liferay again and check log file
   • Expected behavior: only one ERROR trace and no WARN traces are present in log startup
   • Wrong behavior: several ERROR and WARN traces are present in log startup
