Thanks for reviewing, I suspect you are pointing out a potential issue
to look at, not that the problem exists in current implementation.

According to JLS 3.8, the classname(an identifier) can only have
letters, digits, plus '_' and '$'.

The '/' is converted from '.' earlier from, thus there won't be '\'
involved as separator.

Therefore, I think we are safe here.
