If you happen to be reading this file into a Swing text component then you can just use the JTextComponent.read(...) method to load the file into the Document. Then you can use:

textComponent.getDocument().getProperty( DefaultEditorKit.EndOfLineStringProperty );

to get actual EOL string that was used in the file.
