      java version "1.8.0_111"

      Java Driver throws NPE in: 

      at com.mongodb.connection.ClientMetadataHelper.getDriverVersion(ClientMetadataHelper.java:113)
at com.mongodb.connection.ClientMetadataHelper.getDriverInformation(ClientMetadataHelper.java:201)
at com.mongodb.connection.ClientMetadataHelper.addDriverInformation(ClientMetadataHelper.java:182)
at com.mongodb.connection.ClientMetadataHelper.<clinit>(ClientMetadataHelper.java:64)

      We are running the driver in environment where

      InternalStreamConnectionInitializer.class.getProtectionDomain().getCodeSource().getLocation()

      returns null (some strange classloader)
      and it throws in NPE here:

      String path = codeSource.getLocation().getPath();

      It would be better to check it for nullness and for example set driverVersion = "unknown" (as it is being done in case of other errors).
