NOT LIKE filter request not working

Hello!
I am using a JDBC connection to an Oracle database. In principle, everything works, but noticed that when I try to make a request

SELECT * FROM custom_table WHERE custom_field NOT LIKE 'some text'

There is nothing in the results, but if I make a similar request in Oracle, everything is displayed

After talking with our Oracle database specialists and intercepting the request, we noticed that query incoming in Oracle from JDBC by Connect Engine is not NOT LIKE, but just LIKE

Although it is worth noting that even if I send a request like LIKE through Connect Engine - Then the result request appears.

There is a feeling that the Connect Engine somehow does not work correctly with a filter like NOT LIKE, on the Oracle side, an error occurs rather than a NOT exception
