Trying to register JCSAdminBean twice

[dsvensson]

Using gradle 7 with dependencycheck 6.1.5, the following exception is printed when running dependencyCheckAnalyze:

> Task :dependencyCheckAnalyze
Could not register JMX bean.

The task finishes correctly however, so from a user POV it seems to be mostly a cosmetic issue.
