execute ScaleVmCommand due to java.lang.NullPointerException
> During scale vm command, in VmwareResource.java the following line is executed where
there is no value sent in the 'details' map for the configuration parameter 'vmware.reserve.mem'.
because of this NPE is occured.

to VMwareResource.java using VirtualMachineTO.
