      slaves java8 from oracle
      EC2 plugin 1.31
      Launched in VPC in AWS along with Slaves. Open ports 443, 22, 9090 (for slave communication) communication in VPC allowed only using private ip addresses.

      For single element in queue with not slaves attached and master executors set to 0 plugin as designed starts launching spot instances. It does not stop physically until capacity is reached. It still tries until task from queue is picked up by worker that launches after ~3m
