The compiler team's explanation

A multi-line (doc-)comment is unterminated.

Erroneous code example:

/* I am not terminated!

The same goes for doc comments:

/*! I am not terminated!

You need to end your multi-line comment with */ in order to fix this error:

/* I am terminated! */
/*! I am also terminated! */
