We have noticed that when compiling with Atelier (either Atelier itself or sending the code through the REST interface) that the build will fail if all brackets '() {} []' are not closed. This includes brackets opened in comments.
For example, this will fail:
class myclass
{
//if someVar {
}
I do not know if this issue has been fixed or if this issue has been brought up, but it has been a nuisance over here.
