There are gzipped tar files in the extensions/deploy directory - such as BRCMTracing.tar.gz, CAProvider.tar.gz, CAsping.tar.gz, BRCMstruts.tar.gz,

but we are getting messages about the agent is not being able to find the .tar version of these files.

Configuration issue 

Resolution

From Sustaining Engineering:

This error indicates that there might be an older version of  Application or upgraded from very old Wily agent,

The ErrorFeature class somehow gets loaded: java.lang.NoSuchMethodError:

Check if having an older version of Application or upgraded from an older version of Wily Agent.

Also try disable the shared class cache for WAS (-Xshareclasses:none)

Disable Class Sharing by adding '-Xshareclasses:none' to the JVM startup arguments.
