Amster makes confusing message, if you don't provide --acceptLicense parameter for installation OpenAM

If you don't provide --acceptLicense parameter for installation OpenAM , Iam getting message:

am> install-openam --serverurl http://centos6-64.example.com:8080/openam --adminpwd f0rg3r0ck
02/15/2017 03:44:21:703 PM CET: Checking license acceptance...
02/15/2017 03:44:21:704 PM CET: License terms not accepted. Cannot continue. Please add the acceptLicense=true parameter to accept license terms.
Configuration failed - check installation logs!

So I will add "--acceptLicense=true" parameter, but I will get the same message. If I wanted look into install log as is recommended in the error message, but logs are not created.

Expected result

The error message should looks like this:
License terms not accepted. Cannot continue. Please add the "--acceptLicense true" parameter to accept license terms.

And no message: Configuration failed - check installation logs!, because logs does not exist.
