Jikoo created this issue Dec 14, 2014

What steps will reproduce the problem?
Not 100% certain, based on the error I'd guess that a block with an item frame attached was burned and healed.

What version of the product are you using?
CreeperHeal v6.7.9 on Spigot 1.8 git-Spigot-612de46-07c2162

Do you have an error log of what happened?

This error occurs once per second when CreeperHeal attempts to heal the relevant object.

Likely to have been caused by https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/commits/01f0122a9e4ab863595a39ca4dca342f10dcc477

Reverses the direction to find the block to heal in, from my understanding.

Looking at the open issues in Spigot's bug tracker, this may not be worth trying to fix for the near future - looks like item frames have some other issues that still need to be fixed, so more changes could be coming.

@Jikoo_K: Go

ok thanks!

Looks like all the itemframe changes are probably complete, please consider this issue re-opened. I'll try to reproduce it on a test server when I have the time, but I suspect that this can be replicated by burning a block with an item frame on it and air on the opposite side, then waiting for it to heal.

Jikoo posted a comment Mar 3, 2015

This is still a problem. I can replicate it reliably by burning a block with an item frame attached. When it heals, the item frame and content are dropped every heal interval, leading to a dupe bug. When I log out, unloading the chunk, that NPE starts occurring every heal interval.
