Please delete this bug report, it was submitted to the Java bug tracker in error.

When opening a double chest for the first time, the opening-chest sound is doubled with a slight delay. The issue only appears during the first time the double chest is opened and applies every time the game is loaded or a double chest is initially created - on leaving and then entering a world, the issue persists. This bug does not happen with a single chest.

This happens in both creative and survival.
