What steps will reproduce the problem?
1. In some pieces of code which call getVm(vmId, userId) assign false parameter 
as getVm(userId, vmId) which must flip the parameter to getVm(vmId, userId).

The mistake in:
*Class Datacenter:
    |processCloudletStatus(SimEvent ev) (1 statement)
    |processCloudletStatus(SimEvent ev) (1 statement)
    |processCloudletMove(int[] receivedData, int type) (2 statements)
    |processCloudletResume(int cloudletId, int userId, int vmId, boolean ack) (1 statement)
    |processCloudletPause(int cloudletId, int userId, int vmId, boolean ack) (1 statement)
    |processCloudletCancel(int cloudletId, int userId, int vmId) (1)


What is the expected output? What do you see instead?
getVm(vmId, userId)

What version of the product are you using? On what operating system?
Cloudsim 3.0, Mac OSX, Netbeanse 7.0, Ant 1.8.
