"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.

.\elasticsearch.bat提示[2023-08-17T14:30:12,880][INFO ][o.e.x.s.s.SecurityStatusChangeListener] [DESKTOP-QT6GKBM] Active license is now [BASIC]; Security is disabled
