String concatenating bytes turns something like
public static String toString(byte level, int x, int z) {
return level + "*" + x + "," + z;
}
into
public static String toString(byte level, int x, int z) {
return jvmdowngrader$concat(level, x, z);
}
private static String jvmdowngrader$concat(byte var0, int var1, int var2) {
return new StringBuilder().append(var0).append("*").append(var1).append(",").append(var2).toString();
}
StringBuilder.append(byte) doesn't exist...
and so it gives an error of java.lang.NoSuchMethodError: 'java.lang.StringBuilder java.lang.StringBuilder.append(byte)'

This looks fine until you look at the bytecode
StringBuilder.append(byte)
doesn't exist... and so it gives an error ofjava.lang.NoSuchMethodError: 'java.lang.StringBuilder java.lang.StringBuilder.append(byte)'
