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'.

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.
