Issue/Introduction

Messages of concern:

[INFO] [IntroscopeAgent.Agent] JavaAgent JBoss Modules Hack: appending wily to system packages
[INFO] [IntroscopeAgent.Agent] JavaAgent JBoss Modules Hack: failed to set the field

Have you an idea about what field is this message?

We have added the com.wily to system packages

JBOSS_MODULES_SYSTEM_PKGS="org.jboss.byteman,com.wily,com.wily.*"

because our tests in the lab have detected that.

Without this, we have problems with Browser Agent auto injection (the reason is unknown).

Environment

• Release: 10.8
• APM 10.8
• Wildfly 24.0.1 on SUSE 15 SP4
• APM JBOSS Agent 2023.3

Resolution

The messages below are expected. They come for JBoss version 7.x and above.

Nothing to worry about as they are just info messages to inform user on adding our agent packages to JBoss system packages.
