Drag-and-drop of a bib file generate a loop of exceptions

[mlep]

JabRef 5.3--2021-02-08--8a95a82
Linux 4.19.0-14-amd64 amd64 
Java 15.0.2 
JavaFX 15.0.1+1

But already present in:

    JabRef 5.2--2020-12-24--6a2a512
    Linux 4.19.0-14-amd64 amd64 
    Java 15.0.1

• Mandatory: I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

If no database is displayed, dragging-and-dropping a database (i.e. a .bib file) on the main JabRef window causes an "infinite" (at least quite long) loop of exception windows to be displayed. Application has to be killed.

Steps to reproduce the behavior:

1. Open JabRef.
2. Close all databases.
3. Drag-and-drop a .bib file.

Note: A drag-and-drop problem was previously reported for PDF files (issue #7072)

The problem is here

jabref/src/main/java/org/jabref/gui/JabRefFrame.java

Line 578 in 5a11412

openDatabaseList = EasyBind.map(tabbedPane.getTabs(), tab -> ((LibraryTab) tab).getBibDatabaseContext());

In JabRefFrame initDragAndDrop we add a new nromal Tab which indicates loading

jabref/src/main/java/org/jabref/gui/JabRefFrame.java

Line 205 in 5a11412

tabbedPane.getTabs().add(dndIndicator);

@tobiasdiez Is there a method in EasBind where we can add a filter before? e.g. check if it's actually a librarytab instanCE

[tobiasdiez]

jabref/src/main/java/org/jabref/gui/maintable/MainTableDataModel.java

Lines 46 to 49 in 94f4c1e

	entriesFiltered = new FilteredList<>(entriesViewModel);
	entriesFiltered.predicateProperty().bind(
	EasyBind.combine(stateManager.activeGroupProperty(), stateManager.activeSearchQueryProperty(), (groups, query) -> entry -> isMatched(groups, query, entry))
	);

I confirm this is fixed. Great, thank you!
