Field Detail

MSG_JAVADOC_MISSED_HTML_CLOSE

public static final String MSG_JAVADOC_MISSED_HTML_CLOSE

Message key of error message. Missed close HTML tag breaks structure of parse tree, so parser stops parsing and generates such error message. This case is special because parser prints error like "no viable alternative at input 'b \n *\n'" and it is not clear that error is about missed close HTML tag.
