Place vinegar, the water, sugar, salt, juniper berries, bay leaves, and peppercorns in a small saucepan; bring to a boil. Reduce heat to medium-low, and simmer 5 minutes. Remove from heat, and let cool to room temperature.
Place cucumbers, cherries, and shallots in a large bowl or storage container. Add pickling liquid, and let sit about 30 minutes at room temperature. Remove bay leaves, and serve.
