use of com.puppycrawl.tools.checkstyle.api.CheckstyleException in project checkstyle by checkstyle.

the class ConfigurationLoader method parsePropertyString.

 * {@code null} entries in the first list indicate a property
 * reference from the second list.
 *
 * <p>Code copied from ant -

 *
 * @param value     Text to parse. Must not be {@code null}.
 * @param fragments List to add text fragments to.
