Java Edition 16w50a

This page covers a development version that has a major issue under certain conditions.

 

The dedicated server for this version has a security vulnerability in the Log4j library that could be used to perform a remote code execution exploit. It can be addressed by appending a certain JVM argument to the server startup command line.^[1]

16w50a is the first and only snapshot for Java Edition 1.11.1, released on December 15, 2016,^[2][3] which adds iron nuggets, the Sweeping Edge enchantment, the ability to boost elytra with fireworks, and fixes bugs. This is the final snapshot released in 2016.

A pre-release version for 1.11.1 was uploaded to Mojang's server at the same time as 16w50a, titled 1.11.1 in-game. This upload was likely a mistake. 16w50a fixed two bugs from the 1.11.1 pre-release that were not present in the bug tracker.

Iron nuggets

• Can be crafted from iron ingots, but are also received from smelting iron tools and armor.

Sweeping Edge

• Can be applied to a sword to increase the damage of the sweep attack.
  • Level 3 makes the sweep attack damage 75% that of the regular attack damage.

Attack indicator

• When in crosshair mode, the weapon is fully cooled, and a mob or entity is in range of attack, the attack indicator is visible and includes a small exclamation point underneath the crosshair (later changed to a plus-sign (+) in the final release^[4])

Enchantments

• Mending is no longer compatible with Infinity on bows when trying to apply it in Survival or when using the /enchant command.
  • In this snapshot, however, players can still add Mending to an Infinity bow, but not vice versa.
  • The player can also put Mending on an Infinity enchantment book, but not vice versa.
  • Old bows with both enchantments applied still keep their enchantments and remain working as they used to.

Fireworks

• While flying using elytra, using a firework gives the player a boost for a certain amount of time. This emits a particle when in use.
  • Fireworks stay at the players location until they disappear or explode.
  • Longer flight duration on the rocket makes the boost last longer. The player can increase the flight duration of a firework by crafting it with gunpowder in the other slots.
  • Fireworks with an explosion deal damage at the end of their flight.
  • The right-click on a block action for the fireworks is prioritized over the right-click ability in midair. This simply means that when the player looks at a block while flying and right-clicking, the rocket shoots regularly, instead of being used as a boost.
• Firework explosions now hurt surrounding mobs and players.
  • The damage radius of the explosion is about 2-3 blocks and is the same for any shape (large ball, creeper, burst, etc.) and the damage decreases with the distance to the explosion.
  • The damage amount at close range is about 5HP without armor on, and with full diamond armor, it equates to about 1HP.
  • Death message is "[player] went off with a bang".

Furnaces

• Iron and golden tools and armor can be smelted into nuggets. Iron and golden horse armor can also be smelted.
  • Yield 1 iron or golden nugget per item respectively.

Totem of undying

• ID name changed from totem to totem_of_undying.

Statistics

• Removed the 'Junk Fished' and 'Treasure Fished' statistics.

Pistons

• Added a new byte tag source for the piston_extension block entity, which is true if the block represents the piston head itself, and false if it represents a block being pushed.

Arrows

• Added a new integer tag Color to be used by the arrow entity, for displaying the custom potion color of a fired arrow item that had a CustomPotionColor tag.

• Fixed a server-side crash for new players loading into a world.

• 16w50a was previously removed from the launcher for some time, but was added back in September 2018.
• This was the last snapshot and any sort of update to be announced on the Mojang blog.
  • This also happened to be announced after they moved to minecraft.net, despite them saying they would post no more news.
• This was also the last development version to be cross-compatible with a full version of Java Edition.
