Server Implementation

Paper

Server Version

1.21.4

Describe the bug

The error occurs when using /p clear and sometimes ensures that the clear is not successfully completed. the error itself in the console only occurs if you do it correctly

To Reproduce

1. Make a clean Server with the Latest Paper, Plotsquared and FAWE
2. Generate a Default Plotworld
3. claim yourself like 15 plots and merge them all
4. after you merged them use /p clear on one of the plots
5. if everything was made right the error should come in the console

Expected behaviour

No errors

I fixed it by changing the condition as follows:

// Original:
if (lock.writeWaiting || lock.lock.getReadLockCount() > 1 || lock.lock.isWriteLocked()) {

// Fixed:
if (lock.writeWaiting || lock.lock.getReadLockCount() == 1 || lock.lock.isWriteLocked()) {

In:
java/com/fastasyncworldedit/bukkit/adapter/NMSAdapter.java:184

Ah yes, this code should be >= 1
