I'm using Flash Builder 4 to build my AIR application.

For a certain reason, I need to declare my package name in camelcase, and class names in lowercase:

//test.as
package Core { 
   public class test {
   }
}

The folder structure is like this (the dir 'Core' matches the package name):

src/
  Core/
    test.as

However, Flash Builder shows error and it doesn't compile at all, only when I put the package name as 'core' then it compiles.

Does AS3 syntax allow uppercase letters in package name? Or just because Flash Builder implicitly disallows this?
