The quick assist (Convert to 'if-!-return') is not offered in a lambda body at valid 'if' locations. Examples:

package misc.test;

@FunctionalInterface
interface A {
	void run(int n);
}

@FunctionalInterface
interface B {
	A foo(int x);
}

public class Test {
	A fi0 = (n) -> {
		if (n == 0) {	// [1]
			System.out.println(n);
			return;
		}
	};
	
	int fun1(int a, int b) {
		A fi2 = (n) -> {
			if (a == b) {	// [2]
				System.out.println(n);
				return;
			}
		};
		return a + b;
	}

	A fun2(int a, int b) {
		return (n) -> {
			if (a == b) {	// [3]
				System.out.println(n);
				return;
			}
		};
	}

	int fun3(int a, int b) {
		B fi3 = (x) -> (n) -> {
			if (a == b) {	// [4]
				System.out.println(a);
				return;
			}
		};
		return a + b;
	}
}
