Uninformative exception is thrown when using invalid values in the USS "background-color" argument

UI Toolkit

-

How to reproduce:
1. Create a new project
2. Open Window > Package Manager
3. Press "Add Package From disk" in the Package Manager
4. Open the attached "UssError.zip"
5. Add "package.json" files that are in NDocumentation-master > NDocumentation-master > com.vertx.nDocumentationExample and com.vertx.nDocumentation folders
6. Press Window > Example Window
7. Observe the console

Expected Behavior: The informative exception is thrown - with an explanation of what is wrong and where
Actual Behavior: The exception is uninformative - shows that something is wrong but does not give any directions or clues on what could be wrong

Reproducible with: 2019.1.0b1, 2019.2.0a2

Note: The exception is thrown because the script is trying to access the wrong value. The value is in Packages > nDocumentation > Styles > "nDocumentationStyles.uss" on the lines 160 and 180. Changing the value to the valid one eliminates the error. Could not reproduce the issue with 2018.3 and 2017.4 because the user code brakes.

  1. Resolution Note (2019.2.X):

    Problem is due to background-color only supporting rgb, rgba or #hexcode.

    A USS validation system is in the work and will give more informative errors in this case.
