Eclipse project showing issue

Not quite sure if I'm raising this against the right component...

I have a simple source file and format on save setup (with extra configuration). On first save the file turns into this:

===
package pkg;

import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;

enum Color {
	RED, GREEN, BLUE
}


class SB {

	public SB addAll(Object o) {
		return this;
	}

	public SB build() {
		return this;
	}
}


public class RMB {

	private static final Set<Object> x = new HashSet<Object>(Arrays.asList(new Color[] {
		Color.RED,
			Color.GREEN,
		Color.BLUE
	}));

	private static final Object o = new SB()
	.addAll("ABC")
	.addAll("DEF")
	.addAll("GHI")
	.build();

}

===

On second save (just made a whitespace change in the file) the formatting in RMB flips to this:
===
public class RMB {

	private static final Set<Object> x = new HashSet<Object>(Arrays.asList(new Color[] {
			Color.RED,
		Color.GREEN,
			Color.BLUE
	}));

	private static final Object o = new SB()
			.addAll("ABC")
			.addAll("DEF")
			.addAll("GHI")
			.build();

}
===

Another whitespace change and it flips back to the first option, and so on - this is causing real issues for the team here as it constantly shows outgoing git changes when nothing is actually changing. I've attached a zip of the project containing this file and the ui/core prefs.

In terms of save actions I simply opened preferences and in saved actions set it to 'Perform the selected actions on save' and 'Format source code' 'format all lines'. The extra config in ui/core prefs files was supplied to me, I haven't dug into it to see which setting is triggering the problem.
