why testrunner doesn't override project property?

Hello all,

I'm using opensource version

In my soapui-test-project.xml I've created project property authorizationEndpoint=http://localhost:8080

I want override that, so I'm running tests using next command: 

D:\opt\SoapUI-5.3.0\bin\testrunner.bat -PauthorizationEndpoint=http://1.1.1.1:80 D:\code\test\soapui\soapui-test-project.xml

but runner executes tests with defined property in soapui-test-project.xml file but not from commandline

documentation says:

P : Specifies a value of a project property for the test run. The specified value will override the variable's value during the run. Usage: -P<variable>=<value>. If the value includes spaces, enclose the entire argument in quotes. To override several variable values, specify the -P argument several times.

What I'm doing wrong?

Thanks for any help
