Description

If I have an instance named "j-t2", then when I call BaseComputeService#listNodes, I get the following error. The 'j' in the exception seems to result from some manipulation of the instance name.

Caused by: java.lang.IllegalArgumentException: Object 'j' doesn't match dns naming constraints. Reason: Can't be null or empty. Length must be 3 to 63 symbols..

Note: I have only tested this with version 1.8.1 and I am calling jclouds from inside a jenkins plugin.
