RFR: 8203892: Target interface added as marker interface in calls to altMetafactory (original) (raw)

Please review the fix for [1], which is a regression provoked by [2]. The fix can be find at [3]. The regression could be reproduced with this test case:

import java.util.; import java.util.function.; import java.io.*;

class Test {     public static Comparator comparingInt(ToIntFunction<? super T> keyExtractor) {         Objects.requireNonNull(keyExtractor);         return (Comparator & Serializable)             (c1, c2) -> Integer.compare(keyExtractor.applyAsInt(c1), keyExtractor.applyAsInt(c2));     } }

in this case javac generates a BSM to the alternative metafactory, but after the change for [2] the target type was included as one of the marker interfaces. This patch fixes that issue.

TIA, Vicente
