   Greetings.

   Unfortunately, this is correct: the Parser literally swallows any Comments as SPECIAL_TOKENS and removes them from the AST (simply as they do not belong to any Nodes of the AST).

   If you want to keep the Comments, then I recommend to:

   1. build a map of the comments based on the ASCII Position of occurance
   2. parse and deparse your statement (could be a formatter too)
   3. re-insert the comments based on the ASCII Position Map

   You can check out JSQLFormatter, where I have done exactly this (since a Formatter definitely does not want to swallow comments).
