<div dir="ltr">Hi Sam,<div>To be honest I'm not too familiar with the lifecycle of an agent. If your agent uses log4j, then you'd likely need to add the log4j-jboss-logmanager library as well. If your agent does not use log4j then it should be safe _not_ to add it.</div></div><br><div class="gmail_quote"><div dir="ltr">On Wed, Nov 14, 2018 at 8:06 PM Sam Thomas <<a href="mailto:sam.thomas@broadcom.com">sam.thomas@broadcom.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi James,<div><br></div><div>Hmm I see.
