Uberjar 6.5.10 unit testing log level

We recently updated to the 6.5.10 uberjar and started receiving excessively long build logs.  It looks like the unit tests have been set to debug log level and we're getting repeated messages from org.apache.sling.testing.mock.sling.MockAdapterManagerImpl whenever it mocks a sling service.  We haven't found any successful way to control this logging and wondered if this group had any suggestions.
