Hi Josh,
Please reach out to Support via chat/ticket and we can take a look and advise accordingly, as of now only indicates that the Java application running on the Collector is performing an operation that uses reflection in a way that is not permitted. This warning typically appears when the code tries to access internal APIs or private fields/methods in a manner that might not be supported in future Java versions. - not sure if this could be because you may use an EA version or an older version of Collector.
