jabref/jabgui/src/main/java/org/jabref/gui/maintable/MainTableColumnModel.java

Lines 229 to 236 in d1e11e0

	/// This creates a new `MainTableColumnModel` out of a given string
	///
	/// @param rawColumnName the name of the column, e.g. "field:author", or "author"
	/// @return A new `MainTableColumnModel`
	public static MainTableColumnModel parse(String rawColumnName) {
	String[] splittedName = rawColumnName.split(COLUMNS_QUALIFIER_DELIMITER.toString());
	Type type = Type.fromString(splittedName[0]);

rawColumnName is an empty String ''. So there could be multiple ways to fix that, I don't know which one would be correct:

• If rawcolumnName is empty, we don't need to waste the CPU cycles and do not split or call Type.fromString, just return return new MainTableColumnModel(Type.NORMALFIELD, '');
• If rawColumnName should never be empty, we instead need to fix the columns with the empty name
