+ * @deprecated Just use {@link SimpleCharStream} directly. The only difference is
+ *             the tabSize. With PMD 6.27.0 the tabSize is set to 1 for all languages, which
+ *             simplifies calculation of the positions of AST nodes. PMD Designer also
+ *             uses a tabSize of 1. If a mapping from PMD's beginColumn or endColumn to
+ *             the text editor coordinates is needed, this needs to be done manually.
+ *             Before it would only have been correct, if the editor used a tabSize of 4.
