Pistons push entities forward, as do blocks moves by pistons; that the item isn't pushed by the moving block is the problem here. Take a look at gap_fall. png, that has no glass pane that connects to blocks, yet still launched the item out. |

There's your mistake. The issue isn’t with the entity itself. Instead, the item is summoned and pushed by the piston. A few game ticks later, the piston block entity completes its extension. At that point, a block suddenly appears where the item entity was originally located (glass pane instantly connecting upon shape update). Items do not end up inside the collision box, but rather the block ends up where the item is (it also does not happen in gt0, but a couple gt's after). Not a bug |

All other entities are pushed correctly, it's just items that are misbehaving here. Yes them being pushed out of collisionboxes is intended, but they shouldn't end up inside the collision box to begin with, after all, the sugar cane breaks the moment the other block starts moving, so the item shouldn't be appearing inside that block. |

This is NOT a bug. It is a consequence of 2 perfectly intentional features:
It is also NOT related to https://bugs.mojang.com/browse/MC-278182 , as this is not an intended feature, but rather a mistake from mojang developers |

Is this still an issue in the current Minecraft Snapshot 15w49b or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. |

Still happens in the last version. I won't bother updating the information anymore. |

Created an issue regarding chikens falling through hoppers. |

|
And you should make a ticket for each bug |

All bugs are on a list. Confirmed just means we have confirmed it. |

Updated. I thought that once a bug would be 'confirmed' it would remain on a check list until it would be 'fixed'. |

I have discovered that this behavior of items passing through non-full blocks can actually be helpful, like in Practical Uses for example. The half-slab on top of the hopper serves the purpose of avoiding chikens falling through the hopper, like in MC-25365 What would really need an improvement is the physics behind the Drops. |

Confirmed. Happens even when there are solid blocks in the middle. |
