NullPointerException: Profile name must not be null

[mbenitog]

When opening a menu which uses textures:

skull:
   textures: <base64 texture>

The game will throw this exception:

The issue seems to rely on line 49. When 'textures' is used and is not null, 'name' could be null so it should not be accessed without checking first:

CrossplatForms/spigot-common/v1_8_R3/src/main/java/dev/kejona/crossplatforms/spigot/v1_8_R3/Adapter_v1_8_R3.java

Lines 38 to 53 in c619f16

	public void setSkullProfile(SkullMeta meta, @Nullable String name, @Nullable String textures) {
	if (textures == null) {
	if (name == null) {
	throw new IllegalArgumentException("Both name and textures cannot be null");
	}
	meta.setOwner(name); // only name provided
	return;
	}
	// note: providing name and textures but not uuid seems to be invalid according to the server
	GameProfile profile = new GameProfile(UUID.randomUUID(), name);
	profile.getProperties().put("textures", new Property("textures", textures));
	ReflectionUtils.setValue(meta, ClassNames.META_SKULL_PROFILE, profile);
	}
