----------------------------------------
Looks like it fails because of the following:

The exception was thrown from here:
{code}
// Path is within an EZ and we have provided encryption parameters.
// Make sure that the generated EDEK matches the settings of the EZ.
final String ezKeyName = zone.getKeyName();
if (!ezKeyName.equals(ezInfo.edek.getEncryptionKeyName())) {
throw new RetryStartFileException();
}
