Building open jdk 8 from source fails

[Sunbo (Bb)]

I have the same build error as lee json.

I add "import static com.sun.tools.javac.parser.Tokens.Token;" code to fix this error. Who can tell me why?

package com.sun.tools.javac.parser;

import com.sun.tools.javac.code.Source;
import com.sun.tools.javac.parser.Tokens.Comment.CommentStyle;
import com.sun.tools.javac.util.*;

import java.nio.CharBuffer;
import static com.sun.tools.javac.parser.Tokens.Token;
import static com.sun.tools.javac.parser.Tokens.*;
import static com.sun.tools.javac.util.LayoutCharacters.*;
