Using the Voice Over screen reader on Mac OS X, the screen reader will not indicate that there is a editor hint at a certain position. Proposed fix would be to play a sound for warnings and another one for error messages and provide BVI users the possibility to get the message corresponding to the underline read out loud. Steps to reproduce: 
1. start Netbeans IDE 
2. click on a line in the code 
3. start VO (cmd + F5 or setting it to enabled in the preferences menu) 
4. navigate the cursor to a warning or error 
5. no indication is given that there is an error or warning or hint on the line. 
6. use cursor to step through underlined text 
7. no indication is given that there is an error or warning or hint. 
Example 1 (hint): 
public class A {
	public void method() {}
}
public class B extends A{
	public void method() {} // There would be a hint here to add @Overrides
}
Example 2 (error):
public class A {
	poblic void method() {} // Syntax error here that would be displayed by the IDE
}
Example 3 (warning):
public class A {
	public void method() {
        		int x = 0;
      		 x = x;
    	}
