Example 1 with BadEscapementException

use of org.eclipse.n4js.conversion.AbstractN4JSStringValueConverter.BadEscapementException in project n4js by eclipse.

 * valid value. If there is a {@link BadEscapementException} is thrown then there is either a warning or an error
 * produced via the diagnosticProducer.
