"warning: usage of JAVA_HOME is deprecated, use ES_JAVA_HOME"
Future versions of Elasticsearch will require Java 11; your Java version from [C:\Program Files\Java\jdk1.8.0_241\jre] does not meet this requirement. Consider switching to a distribution of Elasticsearch with a bundled JDK. If you are already using a distribution with a bundled JDK, ensure the JAVA_HOME environment variable is not set.
Warning: with JDK 8 on Windows, Elasticsearch may be unable to derive correct
  ergonomic settings due to a JDK issue (JDK-8074459). Please use a newer
  version of Java.
Warning: MaxDirectMemorySize may have been miscalculated due to JDK-8074459.
  Please use a newer version of Java or set MaxDirectMemorySize explicitly.
