Research direction

Start with formats/avro-compact/src/main/java/io/cloudevents/avro/compact/AvroCompactFormat.java around line 90, then inspect the related test at formats/avro-compact/src/test/java/io/cloudevents/avro/compact/AvroCompactFormatTest.java around line 46. Update the ID handling as indicated and use different type and ID values in the test so the bug is detected; run the Avro compact format tests to confirm the fix.

Description

bug

Looks like accidental set of ID to type.
https://github.com/cloudevents/sdk-java/blob/main/formats/avro-compact/src/main/java/io/cloudevents/avro/compact/AvroCompactFormat.java#L90

Should be:

.withId(from.getId())

Test should be fixed as well. Using different values in type and ID of the test event would detect the issue.
