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.

I think it's an empty string that ReferenceTree.getSignature can return, not
null. 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);
