Works fine if creating like this:
byte [] d = {1,2};
String ss = new String( d );
But fails if creating like this:
String ss = new String( {1,2} );
or even this:
String ss = new String( {(byte)1,(byte)2});
What is the problem?

String ss = new String( new byte[]{1,2} );
String ss = new String( {1,2} ); doesn't work because arrays cannot be initialized by simply doing a {} block. It requires the new someThing[] in front of it.

Mind that it's a good practice to identify the encoding being used, e.g. new String(new byte[]{1, 2}, "UTF-8") - otherwise this command is platform specific, using the default charset of the platform

@Rene Well that's correct in that it works. But the question was, why the OP's code fails. And the reason for that is incorrect syntax. You may have mentioned that.
String ss = new String (array of bytes);
we can pass here array of bytes but in
String ss = new String( {1,2} ); {1 , 2} this is not an array and
String ss = new String( {(byte)1,(byte)2}); {(byte)1,(byte)2} this is also not an array
So we can simply use
String ss = new String( new byte[]{1,2} );
