Unlucky formatting for array literals at just above line length

[magicus]

What happened?

The following formatting is produced by Palantir (we run it as a plugin to Spotless), version 2.28.0:

    private static final int[] ACCESSORY_SLOTS = {RING_1_SLOT_NUM, RING_2_SLOT_NUM, BRACELET_SLOT_NUM, NECKLACE_SLOT_NUM
    };

It does not look pretty. :-(

As soon as you add one additional character, it looks much better:

    private static final int[] ACCESSORY_SLOTS = {
        RING_1_SLOT_NUM, RING_2_SLOT_NUM, BRACELET_SLOT_NUM, NECKLACE_SLOT_NUM2
    };

or if you remove two characters:

    private static final int[] ACCESSORY_SLOTS = {RING_1_SLOT_NUM, RING_2_SLOT_NUM, BRACELET_SLOT_NUM, NECKLACE_SLOT_N};

(though I personally disagree with the lack of space surrounding the brace in this case)

What did you want to happen?

I would have expected it to look like in the one character longer example, since the closing brace did not fit on the same line as the opening brace:

    private static final int[] ACCESSORY_SLOTS = {
        RING_1_SLOT_NUM, RING_2_SLOT_NUM, BRACELET_SLOT_NUM, NECKLACE_SLOT_NUM
    };
