There are no clear instructions on how to build and use the latest version of paperBin (with the new features since the last release)

I tried ./gradlew build, but it fails

When I fly fast, my chunks look like this

Unload chunks that only contain dead entities (Maybe also stop sending updates to dead entities, stops death screen spectating)

Putting farm crops / tree decay ticks on a seperate thread would be nice, so you don't have to disable / lower it.

Upon trying to start server (java -Xms128M -Xmx2048M -jar PaperBin.jar Paper.jar), the following error is given:

This happens on an install of CentOS 7, which does not have Glibc v2.18.
Any ideas?

When I was running the jar compiled by my self, it showed me an error

Couldn't fetch jvmti instance (-3)

What should I do to solve this question?

It doesn't seem to be working. Here is my start command:

Using ccspigot and paperbin

needs more rust

Hi, my players noticed a new dupe exploit involving PaperBin on server restarts/crashes. Items are being duplicated by moving things from enderchest to normal chests. I thinks it has something to do with world/player files being saved separately.
Another thing I noticed the server can be crashed more easily when I'm running PaperBin. After the crash I got hs_err files which I suppose unique to PaperBin as I never got them running other builds. The players are also lose their 0.5-1 hour progress which can be dupe exploited too.

Thanks for your work anyway, it's a great project, I hope you're not abandoning that

Release the string you Get

Because the string you received is guaranteed to be valid.

Asynchronous liquid flowing and maybe tps compensation

According to Apache's website here,

Commons RNG provides implementations of pseudo-random numbers generators that are either faster or of higher quality (and sometimes both) than java.util.Random.

Here is a related patch:

I'm just too lazy to do it ¯\(ツ)/¯
