The reason was in `EditorEditorKit` class, `write(Writer out, Document doc, int pos, int len)` method, where translation happens from buffer to Out(Writer Object) if endOfLine is other than '\n' ( which is '\r\n' in windows). In order to write each line till End of line, the string till '\n' is written including '\r' and again endOfLine is written which results in extra Carriage Return. To solve this issue, a Condition is added which checks if previous character to '\n' is '\r', if true then whole string except Carriage Return ('\r') is written, else whole string till before '\n' is written.

If I add '\n' after the string then it would be "\n\r\n" which would be mapped to "\r\n\r\n" resulting in extra space......
