> Java user-defined function (UDF) UDF functions with *Character[]* and *Byte[]* return types are recognized as {*}OTHER{*}, but UDF functions with *char[]* and *byte[]* return types are recognized as *VARCHAR* and {*}VARBINARY{*}. *Character[]* should be consistent with {*}char[]{*}, and *Byte[]* should be consistent with {*}byte[]{*}.
