| Description |
|
Since the console does not have a command named "/version", I've included the output of "version" instead (this is for both spigot and craftbukkit). The bugged tridents which were spawned did not crash the vanilla server, and nor were there any exceptions printed. This is the expected behaviour. This means this a CB/Spigot issue only. Note that World#spawnEntity(Location, EntityType) does not create bugged tridents. The test plugin includes a method to test this as well.
In order to test this bug, please use a clean install of cb or spigot.
The test plugin included can be used to produce the bugged tridents. In order to do so, connect to the server running the test plugin and type "crashmepls" in chat and press enter. A trident projectile will be launched in the direction you are looking. This projectile will be bugged.
Alternatively, a bugged trident projectile can be spawned with the following code: https://gist.github.com/Spottedleaf/c8811c3d13d6a7091591e4ef2c29f89a
In order to produce a non-bugged trident projectile (one which uses World#spawnEntity), connect to the server running the test plugin and type "dontcrashmepls" in chat and press enter. A trident projectile will be launched in the direction you are looking. This projectile will NOT be bugged.
In order to produce crash results, the following conditions MUST be met:
An example of thoroughly following the above steps is here: crash report: https://gist.github.com/Spottedleaf/68cdb7235c0871224629da38061d83b0 server log: https://gist.github.com/Spottedleaf/de5d9405185a4d1fe1a1b507c85c0487 For clarification purposes please note that the crash report and server log are from a single crash, and that it was produced via Spigot.
I've also attached the plugin and source to this issue. |
