Hello Team,
We have recently upgraded oracle JAVA version to below
**java version "1.8.0\_281"**
**Java(TM) SE Runtime Environment (build 1.8.0\_281-b09)**
**Java HotSpot(TM) 64-Bit Server VM (build 25.281-b09, mixed mode)**
After Upgrading elastic search server is not getting started with below errors
Here ES security is not enabled.
Below is the elasticsearch.yml file
