test/jdk/java/util/Collections/CheckedMapBash.java line 193: > 191: m.merge("key", "value", (v1, v2) -> null); > 192: fail("Should throw ClassCastException"); > 193: } catch (ClassCastException ignore) { Since this test is already running with testNG, we should just use its builtin functionalities: @Test(groups = "type_check") public static void testTypeCheck() { Map m = Collections.checkedMap(new HashMap<>(), Integer.class, Integer.class); Assert.assertThrows(ClassCastException.class, () -> m.merge("key", "value", (v1, v2) -> null)); Assert.assertThrows(ClassCastException.class, () -> m.merge("key", 3, (v1, v2) -> v2)); } In addition, the checked map tests are in general, only checking the map functionality works without checking if the type checking functionality works. But adding a comprehensive test for checking functionalites would be much more work and is out of this patch's scope, so you don't need to worry about it. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/18141#discussion_r1515507158
