Hamcrest test shows that a card contains all records from another card

I want to check that the card contains a specific set of records. It may contain other entries that are not in expectedMap. I currently have the following statement:

assertThat(expectedMap.entrySet(), everyItem(isIn(actualMap.entrySet())));

Although this works, the error message it prints is confusing because the expected and received arguments were canceled from normal use. Is there a better way to write this?
