---------- BEGIN SOURCE ----------
package com.foo.bar;

import org.apache.http.Header;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpRequestBase;
import org.junit.jupiter.api.Test;

class CompileErrorTest {

    public enum AuthType {NONE, BASIC_HTTP, BEARER}

    private final Function<AuthType, Optional<Header>> authHeaderApplier = authType -> Optional.empty();

    // Leads to

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Using lambda instead of method reference:
private <T extends HttpRequestBase> T applyAuth(@Nonnull final T request) {
        authHeaderApplier.apply(AuthType.BASIC_HTTP).ifPresent(header -> request.addHeader(header));
        return request;
    }
Or using java above 8: 11, 17 works perfectly.
