getEthernetDriver exception in Kura no network version #81

Closed dwoodard1 closed 8 years ago

dwoodard1 commented 8 years ago

This bug was originally reported at https://bugs.eclipse.org/bugs/show_bug.cgi?id=480606.

Original message:

The nn version will throw out an exception when booting up, caused by not able to get EthernetDriver which is used to get eth0 MAC address for default MQTT client-id (if leave empty in UI setting).

Suggest to add ethtool dependency if possible.

I can confirm that I am also encountering this. Stack trace is as follows:

Hi Doug, Are you having this issue in Kura 1.4.0? Thanks. Matteo

dougmeredith commented 8 years ago

Sorry Matteo, I should have specified that upfront. 1.3.0, on Raspbian Jessie, with Oracle 8 JDK from the Raspbian repository.

MMaiero commented 8 years ago

Have you had the chance to test the 1.4.0? (It's not released yet, you have to compile it from source)

MMaiero commented 8 years ago

Closing. It should be fixed in release 1.4.0
