val assigning incorrect class to Arrays.asList() in Eclipse

[dastamatis]

In the latest version of lombok and Eclipse, val is incorrectly assigning variable "x" to Object instead of List<Class<? extends java.io.Serializable>> in the code below:

package com.github.rzwitserloot;

import java.math.BigDecimal;
import java.util.Arrays;
import java.util.List;
import lombok.val;

public class ValBug {
	public static void main(String[] args) throws Exception {
		val x = Arrays.asList(String.class, BigDecimal.class);
		for (val y : x) {
			
		}
	}
}

Is that a regression; did a previous version of lombok do this differently?

Is is only in Eclipse, or also on javac?

I tried it with 1.14.6, 1.16.10, 1.16.16, and latest version 1.18.4, both in Eclipse and on the command line.

Error is the same:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
Type mismatch: cannot convert from List<Class>> to List<Class<? extends Object>>

And by "on the command line", I mean I compiled it with javac in a terminal window (not from Eclipse's UI).

Wow, good catch.

I cannot reproduce the problem using 1.18.6 and javac 11.

[rspilker]

Oh, and we will not create List<Class<? extends Serializable>> but List<Class<? extends Object>>.

Can you verify your Eclipse works with the latest edge release?

[dastamatis]

Yup, works now. Thanks for the fix!
