Could not get lock /var/lib/dpkg/lock

Seems like following step or the one before is leaving the dpkg lock file behind.

Obviously not the most elegant solution but ensuring the dpkg/lock fileis removed before the debian | ensure Java is installed worked.

amazon-ebs: TASK [oracle-java : debian | set license as accepted] **************************
    amazon-ebs: changed: [127.0.0.1]
    amazon-ebs:
    amazon-ebs: TASK [oracle-java : debian | remove apt-get lock] ******************************
    amazon-ebs: changed: [127.0.0.1]

    amazon-ebs: TASK [oracle-java : debian | ensure Java is installed] *************************

Definitely the step causing the troubles is:

debian | set license as accepted

@mauriziod this seems to indicate that you had another process running apt-get update or apt-get install.

during my tests I haven't found this problem yet.
