public class JSyntaxTextArea
extends org.fife.ui.rsyntaxtextarea.RSyntaxTextArea

Utility class to handle RSyntaxTextArea code It's not currently possible to instantiate the RSyntaxTextArea class when running headless. So we use getInstance methods to create the class and allow for headless testing.
