    Description

      Code highlighting and error checking stop working when method reference passed as a parameter to method not on it's proper place. Page and/or application reload don't help.

      IDE said that I have found a bug in the application.

      Annotation: An error occurred during parsing of 
      'C:\Users\User\Documents\NetBeansProjects\MusicWaves\src\java\by\musicwaves\dao\UserDao.java'.

      Please report a bug against java/source and attach dump file 
      'C:\Users\User\AppData\Roaming\NetBeans\12.4\var\log\UserDao_150.dump'.

      From UserDao I call method

      public <T> List<T> processMultipleResultsSelectRequest(
                  String sql,
                  PreparedStatementContainerInitializer statementInitializer,
                  Supplier<T> entityCreator,
                  EntityInitializer<T> entityInitializer) throws DaoException {
      ...
      }

      I pass reference to constructor as entityCreator parameter.
      If I place parameters correctly:

      requestHandler.processMultipleResultsSelectRequest(
              "some SQL String",
              null,
              User::new,
              this::initUser);
      

      , everything works just fine.

      However, I've found that if I swap parameters by mistake and do something like that:

      requestHandler.processMultipleResultsSelectRequest(
              "some SQL String",
              User::new,
              null,
              this::initUser);
      

      , instead of highlighting my mistake, I get an error message from IDE.

       

      IDE log and UI log are attached in case there is something useful inside. I copied text from them a bit earlier so there might be mentioned some other UserDao_XXX.dump.

      UserDao_150.dump attached since it was requested by IDE.
