No. Please use Java 8. Nutch requires Java 8, see default.properties. The Dockerfile is outdated. If possible please open a Jira issue to update it.
The error is really weired: NutchJob extends org.apache.hadoop.mapreduce.Job, so there should be no verification [1] error. I'm not able to reproduce it. Could you explain more in which environment Nutch is executed and how you launch it? Ev. try with "java -Xverify:none" (for bin/nutch set the environment variable NUTCH_OPTS=-Xverify:none) to see what happens.
