Description

When I call the jdbc close method, I found that the phoenix link still exists and is not closed.
The code is as follows：

public class TestHbaseClose {
    public static void main(String[] args) {
        Connection conn=null;

        for (int i = 0; i < 5; i++) {
            try {
                conn= PhoenixConnectionTest.getConnPhoenix();
                System.out.println("Before is "+conn);
                Thread.sleep(8000);
                conn.close();
                System.out.println("After is "+conn);
                System.out.println(conn.isClosed());
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
}

The results of the print are as follows:

Before is org.apache.phoenix.jdbc.PhoenixConnection@2fb5fe30
After is org.apache.phoenix.jdbc.PhoenixConnection@2fb5fe30
true
Before is org.apache.phoenix.jdbc.PhoenixConnection@14bae047
After is org.apache.phoenix.jdbc.PhoenixConnection@14bae047
true
Before is org.apache.phoenix.jdbc.PhoenixConnection@466d49f0
After is org.apache.phoenix.jdbc.PhoenixConnection@466d49f0
true
Before is org.apache.phoenix.jdbc.PhoenixConnection@40021799
After is org.apache.phoenix.jdbc.PhoenixConnection@40021799
true
Before is org.apache.phoenix.jdbc.PhoenixConnection@64f555e7
After is org.apache.phoenix.jdbc.PhoenixConnection@64f555e7
true

Why is this? Is there a bug fixes in version 4.8.0?
But the following link mentions this question:
