The exception can be thrown on attempt to get value of derived attribute {{logFiles}} in {{FileLoger}}. As result, REST calls to {{FileLoger}} can end-up in error as below
{code}
{
"errorMessage" : "Comparison method violates its general contract!"
}
{code}
Broker REST service call can be affected if depth parameter value is 1 or greater.
The Web Management Console invokes broker REST service with depth=1 and on running into the issue the information on Broker tab is not rendered.
