Description:
It's a behavior that appears when using maven with -X property in an unherited project, I can't know if it's a real problem or only a bad log.

1) Make a project
2) In it's project.properties, put a property that uses an undefined property, as an exemple

my.foo.property=${undefined.property}

3) Execute a maven goal : all goes well

4) Make a new project inheriting this one

5) Call maven in debug mode, in the log I have a  :

with no detail about the expression that causes the problem

In MavenUtils, the line says :

 String literalValue = (String) value;

and (after a quick look) the /value/ (it's the value of ${undefined.property}),  in this case is not a String but a 
org.apache.commons.jelly.expression.jexl.JexlExpressionFactory$ExpressionSupportLocal@15bdc50[expression:undefined.property]

It sounds like in this (inherited) case the property value is not evaluated as it should be.

I don't know if it's a real problem or simply a log issue, but if it's simply a log problem it should be removed or the log should be cleaner.
