Weird "illegal start of expression" error in Netbeans

In the following programs, command is a byte array field in Apdu class. The problem is that my IDE (Netbeans) mark the line of 

apdu.command = {(byte) 0x00, (byte)0xa4, (byte) 0x00, (byte) 0x00};

As error, with the message illegal start of expression, while it is okay to use the following instead:

byte[] bytes = {(byte) 0x00, (byte) 0xa4, (byte) 0x00, (byte) 0x00};
apdu.command = bytes;

What's wrong with the first programs?

array syntax {} can only be used for initialization not for assignment.

you need to use apdu.command =new byte[] {(byte) 0x00, (byte)0xa4, (byte) 0x00, (byte) 0x00};.

You need to initialize the array variable with :

apdu.command = new byte[] {(byte) 0x00, (byte)0xa4, (byte) 0x00, (byte) 0x00};

The initialization you tried is only valid in array declaration expressions.
