Product Version: NetBeans IDE 6.9 (Build 201006101454) Java: 1.6.0_20; Java HotSpot(TM) 64-Bit Server VM 16.3-b01 System: Windows 7 version 6.1 running on amd64; Cp1252; en_GB (nb) I'm getting false positives for the IncompatibleMask hint when using values in arrays. The following code demonstrates this: public class Main { public static void main(String[] args) { byte[] a = {Byte.MAX_VALUE}; // displays a hint that incorrectly says the expression is always false System.out.println((a[0] & 32) == 32); // if you copy the value out of the array then no hint is displayed byte b = a[0]; System.out.println((b & 32) == 32); } } The first print statement causes hint that says "IncompatibleMask: (a[0] & 32) == 32 is always false". The second print statement causes no hint to be displayed. Both expressions evaluate to true.
