java - Unrecognized Hibernate Type when using enum in query -

i have entity class set of enums:

@entity public class {      public enum type{         first_enum((short)1),         second_enum((short)2);          private short id;          private type(short id) {             this.id = id;         }          public short getid() {             return id;         }     }      @collectiontable(name="table_name", joincolumns=@joincolumn(name="something_id"))     @column(name="type")     private set<type> types;      ... //other props + getters , setters } 

for enum made converter (whole converter package loaded @entityscan annotation) :

@converter(autoapply=true) public class typeconverter implements attributeconverter<type, integer> {      @override     public integer converttodatabasecolumn(type st) {         //implementation     }      @override     public type converttoentityattribute(integer i) {         //implementation     } } 

now when try use enum in query

... , {packagename}.something$type.first_enum member of {someobject}.something.types ... 

i stumble upon following error:

org.hibernate.queryexception: unrecognized hibernate type handling query constant ({package}.something$type.first_enum); expecting literaltype implementation or attributeconverter 

does got clue why cannot use enum in query? somehow seems enum not known hibernate. don't understand why, because class loaded when start application.
