database - DBCException: SQL エラー [50000] [HY000]: 一般エラー

Question

H2データベース用のDbeaverエディターを使用してこの手順をコンパイルしようとしていますが、コンパイルされず、エラーが発生します

スクリプトは

Create Alias InsertDepartment AS $$ 
 int InsertDepartment(Connection conn,String p_eName,String p_aName ,int p_sec_id) throws Exception {

 String IdQuery="SELECT max (id)+1 FROM DEPARTMENTS";
 java.sql.ResultSet rs = conn.createStatement().executeQuery(IdQuery);
 int id =rs.getInt(1);

 String query=" INSERT INTO DEPARTMENTS (ID,E_NAME,A_NAME,SEC_ID) values ("+id+","+p_eName+","+p_aName+","+p_sec_id+")";
 rs = conn.createStatement().executeQuery(query);
   int resultInt= rs.getInt(1);
   return resultInt;
}
$$;

そして私が得るエラーは

DBCException: SQL Error [50000] [HY000]: General error: "java.lang.UnsupportedClassVersionError: org/h2/dynamic/INSERTDEPARTMENT : Unsupported major.minor version 52.0"; SQL statement:

インターネットでストアドプロシージャの良い例をネットで見つけるために多くのことを試みましたが、H2サイトでhttp://h2database.com/html/features.html#user_defined_functionsを読んだことはあまりありませんが、とても貧弱ですCRUDの例はありません
