json loading error though paintweb works fine

[GoogleCodeExporter]

What steps will reproduce the problem?
1. download release zip and unzip it.
2. delete src, samples and etc, just keep release files
3. add to my own javaee web content.

What is the expected output?
paintweb loaded without any error, but i always get error that 'not 
well-formed' and 'syntax error' when loading config json, language json and 
color window json though paintweb works so well.

What do you see instead?
no error from browser debug.

What version of the product are you using? On what operating system and
which Web browser?
lastest, Win7, FF 31.0

Check your webserver configs. Check the network request and responses. In 
Firefox, open devtools (press f12), then go to network monitor, reload 
paintweb, and check the requests that load the json files. See response 
headers, check response bodies, etc. Also go to devtools settings and disable 
caching, for less confusion.
