You are absolutely right. I got immersed in CommentHelper.normalizeSignature so much so that I forgot about separating function of whitespace in positional argument parsing. > Yes, it can.

To check that, I modified DCReference as follows and ran the tests (including TestTagMisuse), which all passed: DCReference(String signature, JCTree.JCExpression moduleName, JCTree qualExpr, Name member, List<JCTree> paramTypes) { - this.signature = signature; + this.signature = Objects.requireNonNull(signature); ------------- PR: https://git.openjdk.java.net/jdk/pull/3754
