In section 3.10.6 Text Blocks of the updated spec;

However, the JEP 378 description reads "The opening delimiter is a
sequence of three double quote characters (""") followed by zero or more
white spaces followed by a line terminator.
javac uses the Character.isWhitespace test for characters following the
opening three double quote characters.
Character::isWhiteSpace allows not only the JLS definition of whitespace
-- space, tab, and FF -- but also LF and CR. So, javac would accept """
followed by some LF/CR characters (its idea of "zero or more white
spaces") followed by a final LF/CR character (the "line terminator", at
least according to the definition in JLS 3.4; can't find a definition in
the API). That can't be right -- it extends the delimiter line into the
content, so to speak.
