See https://issues.apache.org/jira/browse/HARMONY-6461, At present when load a charset with the given charset name, Charset will cache all alias of that charset. However one alias maybe belong to different charsets. This design will cause alias conflict. Charset solve this issue now by hard coding all conflict alias. I think the correct way is only cache the given charset name and its canonical name. If you have any suggestion? Thanks a lot!
