I'm using logback for logging to database using DBAppender. I've configured a connection pool of 20 connections. The problem is that DBAppenderBase closes the Connection-objects after each insert, which is undesired as the connection pool implementation should take care of the life cycle of the connections.

public abstract class DBAppenderBase<E> extends UnsynchronizedAppenderBase<E> {
...
...
public void append(E eventObject) {
...
...
} finally {
      DBHelper.closeConnection(connection);
}
...
