JS minification is not working for some clientLibs

Hi All,

I'm using this below property to minify the JS. But, it is working for some clientLibs and it not working for some ClientLibs. Can someone have any idea in this issue?

jsProcessor: ["default:none", "min:gcc;compilationLevel=advanced"]

Also, I tried with advanced, simple, whitespace. still no luck.

Thanks,

Vijay
