ArrayIndexOutOfBoundsException #246

Closed File14 closed 3 years ago

File14 commented 3 years ago

Hello,

We get an ArrayOutOfBoundsException when we try to add an object to the Object2IntOpenHashMap. We are currently using FastUtil 8.5.2. Do you know what causes the exception to be thrown?

Error:

The following code is executed from the Geyser project that throws the exception: CACHED_BLOCK_ENTITIES.put(new Position(position.getX(), position.getY(), position.getZ()), blockState);

Most likely concurrent access. Try to synchronize the map.
