    Hello, in my random teleport plugin, when i execute the command to random teleport in the nether, it make the server crash.

    This is the teleportutils class
    Code:
    package nepliozplugins.randomteleport;import org.bukkit.*;import org.bukkit.block.Block;import org.bukkit.entity.Player;import java.util.HashSet;import java.util.Random;public class TeleportUtils {

static RandomTeleport plugin; public TeleportUtils(RandomTeleport plugin) {
this.plugin = plugin;}

public static HashSet<Material> bad_blocks = new HashSet<>(); static{
bad_blocks.add(Material.LAVA);bad_blocks.add(Material.STATIONARY_LAVA);bad_blocks.add(Material.FIRE);bad_blocks.add(Material.WATER);bad_blocks.add(Material.STATIONARY_WATER);}

public static Location generateLocation(Player player){
Random random = new Random(); int x = 0; int y = 0; int z = 0;World world = player.getWorld(); boolean useWorldBorder = plugin.getConfig().getBoolean("world-border"); if (useWorldBorder) {
int borderSize = (int) world.getWorldBorder().getSize() / 2;x = random.nextInt(borderSize * 2) - borderSize;z = random.nextInt(borderSize * 2) - borderSize;x += world.getWorldBorder().getCenter().getX();z += world.getWorldBorder().getCenter().getZ();Location testLocation = new Location(world, x, 0, z); if (!world.getWorldBorder().isInside(testLocation)) {
return generateLocation(player);}
} else {
int maxDistance = 25000;x = random.nextInt(maxDistance) - maxDistance / 2;z = random.nextInt(maxDistance) - maxDistance / 2;}

y = 150;Location randomLocation = new Location(world, x, y, z);y = randomLocation.getWorld().getHighestBlockYAt(randomLocation);randomLocation.setY(y); while (!isLocationSafe(randomLocation)) {
if (useWorldBorder) {
double borderSize = world.getWorldBorder().getSize() / 2.0;x = random.nextInt((int)borderSize * 2) - (int)borderSize;z = random.nextInt((int)borderSize * 2) - (int)borderSize;} else {
int maxDistance = 25000;x = random.nextInt(maxDistance) - maxDistance / 2;z = random.nextInt(maxDistance) - maxDistance / 2;}

randomLocation = new Location(world, x, y, z);y = randomLocation.getWorld().getHighestBlockYAt(randomLocation);randomLocation.setY(y);}

return randomLocation;}

public static boolean isLocationSafe(Location location){

int x = location.getBlockX(); int y = location.getBlockY(); int z = location.getBlockZ();Block block = location.getWorld().getBlockAt(x, y ,z);Block below = location.getWorld().getBlockAt(x, y - 1, z);Block above = location.getWorld().getBlockAt(x, y + 1, z); return !(bad_blocks.contains(below.getType()) || (block.getType().isSolid()) || (above.getType().isSolid()));}

}
    Thanks

    I also got the server crash logs
