>From Tomcat Embedded Core 9.0.26:
@Override
protected void doClose() {
if (log.isDebugEnabled()) {
log.debug("Calling [" + getEndpoint() + "].closeSocket([" + this +
"])", new Exception());
}
Which will log something like:
DEBUG [http-nio-8080-exec-2]
org.apache.tomcat.util.net.NioEndpoint

To print the stack trace next to the message? Why not only print the stack
trace next to the log message using
org.apache.commons.lang3.exception.ExceptionUtils.getStackTrace for
example? The presence of the `java.lang.Exception: null` in the logs is a
bit misleading and confusing.
