bug#41396: java-kafka-clients fails tests

[Ricardo Wurmus]

java-kafka-clients has a failing test:

    [junit] Running org.apache.kafka.common.network.SslTransportLayerTest
    [junit] SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
    [junit] SLF4J: Defaulting to no-operation (NOP) logger implementation
    [junit] SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for 
further details.
    [junit] Tests run: 31, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 
8.072 sec

The SLF4J failure seems to be unrelated (other tests also have this warning).
