   Greetings.

   A lots of API has changed between 4.4 and 4.6 in order to streamline VALUES (..) statements.
   The easiest way to figure out the AST is using JSQLFormatter, which can visualize the Tree of Java Objects:

   Recommendation: Checkout PR #1754 which will allow for

       @Test
       void testIssue1765() {
           String sqlStr = "INSERT INTO mytable (col1)\n"
                           + "VALUES ( 1 )";
   
           Insert insert = new Insert()
                               .withTable( new Table("mytable") )
                               .withColumns( Arrays.asList(new Column("col1")) )
                               .withSelect( new Values().addExpressions(new LongValue(1)) );
   
           assertStatementCanBeDeparsedAs(insert, sqlStr,true);
       }

   If you use Release 4.6 then your code will look like this:

       @Test
       void testIssue1765() {
           String sqlStr = "INSERT INTO mytable (col1)\n"
                           + "VALUES ( 1 )";
   
           Select select = new Select()
                                   .withSelectBody( new ValuesStatement().addExpressions( new LongValue(1)) );
   
           Insert insert = new Insert()
                                   .withTable( new Table("mytable") )
                                   .withColumns( Arrays.asList(new Column("col1")) )
                                   .withSelect(  select );
   
           assertStatementCanBeDeparsedAs(insert, sqlStr,true);
       }
