Some issues I find when updating the demos to support JSON format module 
info.

1. We need to add some document on how to write JSON format module info. 
I have to look into source code to learn how module-info.json structures 
and how to add modifiers.

2. Error message is not clear enough. I typed "jdk.desktip" by mistake 
in requires section in modulebrowser, and then I got an error said 
"modulebrowser cannot be solved" when installing the module into module 
library. It should tell "jdk.desktip cannot be solved" instead.
