[PR] Revert "AMBARI-26142: JDK17 support for Ambari-metrics" [ambari-metrics]

JiaLiangC opened a new pull request, #142:
URL: https://github.com/apache/ambari-metrics/pull/142

   Revert "AMBARI-26142: JDK17 support for Ambari-metrics (#134)"
   
   This reverts commit 667fa9acc5aa96b50245b7be0d862b26815ac45e.
   
   Reason for revert:
   The JDK17 upgrade for Ambari-metrics has caused compatibility issues with various component sinks (Hadoop, HBase, etc.) that are still running on JDK8. Since Ambari-metrics produces JAR files that serve as plugins for these components, the JDK17-compiled sinks are not compatible with the JDK8 runtime environment of the host components.
   
   Specifically, when Hadoop (which runs on JDK8) attempts to load the metrics sink compiled with JDK17, it fails to start due to bytecode incompatibility issues. This incompatibility affects multiple components that integrate with Ambari-metrics.
   
   We need to revert to the JDK8-compatible version until we can implement a solution that maintains backward compatibility with JDK8-based components or until all dependent components are upgraded to support JDK17.

   Actually we shouldn't revert JDK17 changes. Since Ambari-metrics is running on JDK17, it will encourage other dependent components to upgrade JDK to JDK17. 
   Also, they can use older ambari-metrics which is running on JDK8.
   
   @brahmareddybattula @arshadmohammad @virajjasani what's your view on this? how should be handle this?
