Build/compilation issue with wildcard types

Following is some sample code to replicate the issue:

import java.util.List;

public class Tester {
    <T extends List<? extends Entry<?, ?>>> Entry<?, ?> test(T input) {
        return ConcreteEntry.from(input.get(0));  // Error here
    }

    public static void main(String[] args) {
        Tester tester = new Tester();

        System.out.println(tester.test(List.of(new ConcreteEntry<>("a", 1))));
    }

}

interface Entry<K, V> {
    K getKey();

    V getValue();
}

class ConcreteEntry<K, V> implements Entry<K, V> {
    private final K key;
    private final V value;

    public ConcreteEntry(K key, V value) {
        this.key = key;
        this.value = value;
    }

    public static <K, V> ConcreteEntry<K, V> from(Entry<K, V> entry) {
        return new ConcreteEntry<>(entry.getKey(), entry.getValue());
    }

    @Override
    public K getKey() {
        return key;
    }

    @Override
    public V getValue() {
        return value;
    }

    @Override
    public String toString() {
        return this.key + "=" + this.value;
    }
}

The test method throws the error The method from(Entry<K,V>) in the type ConcreteEntry is not applicable for the arguments (capture#1-of ? extends Entry<?,?>) Java(67108979). The expected behaviour is correct compilation. However, enabling the "java.jdt.ls.javac.enabled" works, but is not an ideal solution.

This occurs with the latest Language Support for Java(TM) by Red Hat - v1.42.0.

使用 Language Support for Java v1.42.0，通过 issue 中的 Java 示例复现报告的诊断：先使用正常的编译器路径，然后启用 java.jdt.ls.javac.enabled。比较两次结果，并确认通配符类型示例在修正后的路径上可以无错误地编译。
