Comment 3 Victor Zverovich 2012-04-17 07:15:57 EDT

I have a similar issue (hover doesn't display values of variables) for local variables and parameters in methods of generic classes. Here is a small example that reproduces the issue:

class A<T> {
    T f(T t) {
        return t;
    }
}

class B {
    Integer f(Integer t) {
        return t;
    }
}

public class App {
    public static void main(String[] args) {
        new A<Integer>().f(1);
        new B().f(1);
    }
}

If you break in B.f and hover over t, the type and value (1) information is displayed in the tooltip.

However, if you break in A<T>.f and hover over t, no value is reported in the tooltip, only the following text: T t - A.f(T)

Same with the simpler case as well:

public class DebugHoverBug {
	public static void main(String[] args) {
		Data d= new Data();
		System.out.println(d.i);
		System.out.println(d.s);
	}
}
class Data {
	int i= 1;
	String s= "bug";
}

I really can't stand this bug,
Why do you want to display value is so troublesome, I just want to hover to see the value directly.
Instead of looking in other windows, I don't want to use a watch or the like.
In contrast to chrome, the value of the variable is displayed directly in the editor, which is the most convenient.
If you can, I hope eclipse can also achieve such a function.
But before this, I hope to hover directly to see the value of the variable.
Thank you!

Eclipse is working on Code mining feature which will enable displaying of values without hovering.

I have a fix.

To reproduce, try to run this snippet in debugger and hover over "text" values.

public class DebugTest {

	private String text = "Hello";

	public static void main(String[] args) throws Exception {
		new DebugTest().doStuff();
	}

	public void doStuff() {
		new Runnable() {
			@Override
			public void run() {
				System.out.println(text); // bp here
				new Runnable() {
					@Override
					public void run() {
						System.out.println(text); // bp here
					}
				}.run();
			}
		}.run();
		new InnerClass().doInnerClassStuff();
	}

	class InnerClass {
		public void doInnerClassStuff() {
			System.out.println(text); // bp here
		}

	}
}
