A lot of new logs in the code that seems to have no obvious errors

[mchistovib]

Describe the bug
There are several logs printed now by qt that weren't there before.
Type 1:

QString::arg: Argument missing: QList<ibkr::model::NewsQListModel*>, ibkr::model::NewsQListModel*
QString::arg: Argument missing: QList<ibkr::model::GlobalAccountSelectorModel::AccountListItem*>,ibkr::model::GlobalAccountSelectorModel::AccountListItem*
QString::arg: Argument missing: QList<JObjectWrapper>, JObjectWrapper
QString::arg: Argument missing: QSet<QString>, QString
QString::arg: 2 argument(s) missing in QHash<int,jclient::ExchangeCurrency*>

Type 2:

QT_QUICK_CONTROLS_TEXT_SELECTION_BEHAVIOR ""
QT_QUICK_CONTROLS_TEXT_SELECTION_BEHAVIOR ""

Type 3:

QWebEngineCertificateError is neither a QObject, nor default- and copy-constructible. You should not use it as a QML type.
QWebEngineFullScreenRequest is neither a QObject, nor default- and copy-constructible. You should not use it as a QML type
QWebEngineLoadingInfo is neither a QObject, nor default- and copy-constructible. You should not use it as a QML type.

To Reproduce
Shows up every time.

Expected behavior
I believe type 1 is some error message missing parameters, type 2 is some debug loging, and type 3 could be some error

Screenshots
If applicable, add screenshots to help explain your problem.

System (please complete the following information):

• OS: Windows
• Java version 11
• QtJambi version 6.4 (didn't test on other versions)
• Qt version 6.4

Type 1 fixed

Type 2:
In QQuickTextField native code is a debug outprint

qDebug() << "QT_QUICK_CONTROLS_TEXT_SELECTION_BEHAVIOR" << qgetenv("QT_QUICK_CONTROLS_TEXT_SELECTION_BEHAVIOR");

That's not QtJambi-related.

[omix]

I actually don't know why QWebEngineCertificateError and the other classes should cause the exceptions anyway.
What qml type registration method do you use when the error occurs?

[mchistovib]

We only use QWebEngineCertificateError in QWidgets part of ui:

m_webEngineView = new QWebEngineView(this);
QWebEnginePage page = new QWebEnginePage(m_webEngineView);
// this is needed to make it load under work proxy, ignores all ssl errors
page.certificateError.connect(QWebEngineCertificateError::acceptCertificate);

We don't have any usages of QWebEngineFullScreenRequest and QWebEngineLoadingInfo anywhere in our code

@omix I can redpoduce it even in basic qml with QtWebEngine(more detailed erros mesages because I am running this with QtJambi debug version)

Perhaps the difference is that we are calling these lines before creating QApplication?

QtWebEngineQuick.initialize();
QtUtilities.initializePackage("io.qt.webengine.widgets");

[omix]

You don't need this line: QtUtilities.initializePackage("io.qt.webengine.widgets");
It's called by QWebEngineView class initializer anyway.

[omix]

We only use QWebEngineCertificateError in QWidgets part of ui:

m_webEngineView = new QWebEngineView(this);
QWebEnginePage page = new QWebEnginePage(m_webEngineView);
// this is needed to make it load under work proxy, ignores all ssl errors
page.certificateError.connect(QWebEngineCertificateError::acceptCertificate);

We don't have any usages of QWebEngineFullScreenRequest and QWebEngineLoadingInfo anywhere in our code

The message is obviously not logged in QtJambi. Actually, in QtJambi, the message "Class is neither a QObject, nor default- and copy-constructible." only appears as an exception after calling QQml.register.

[omix]

QtWebEngineQuick.initialize();

is necessarily called before application init. So far so good.
