Loading the UI the create an S3 blobstore, the nexus.log is spammed with 13 of these WARN log messages each time:
2020-10-02 17:30:59,050-0300 WARN [qtp781624647-52] admin com.amazonaws.auth.profile.internal.BasicProfileConfigLoader - Your profile name includes a 'profile ' prefix. This is considered part of the profile name in the Java SDK, so you will need to include this prefix in your profile name when you reference this profile from your Java code.
When creating/saving an actual blobstore, there are an additional 40-50 of these identical messages.
Do not spam the nexus.log with WARN level messages by default when the end user can do nothing about solving the cause of the WARN messages. Fix the root cause of these messages.
