Parsing error

Netbeans highlights an error on below working code:

<?php
class TestClass {
    const OP_COMMANDS = array(
        "a" => 11111,
        "b" => 22222
    );
    public function output() {
        $v = TestClass::OP_COMMANDS["a"];
        return $v;
    }
}

$t = new TestClass();
print $t->output();

Currently a parsing error appears on the following line:
$v = TestClass::OP_COMMANDS["a"];

The code runs correctly without any error. I have attached the screenshot to show it well.
