[wujastyk]

JabRef version

JabRef 5.0-dev--snapshot--2019-03-03--master--094a0395e
Linux 4.15.0-45-generic amd64
Java 1.8.0_201

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

Steps to reproduce the behavior:

1. Show an entry preview by selecting an item and pressing F2
2. Select Edit / Copy ... / Copy Preview
3. The "Exception Details" window pops up.
4. Nothing is copied to the buffer.

There is an old SwingWorker CitatinStyleToClipBoardWorker which needs to be replaced by a Java FX BackroundTask/

Should be fixed in the latest master. Available in a couple of minutes.

JabRef 5.0-dev--snapshot--2019-03-08--master--c16f733b8 Linux 4.15.0-46-generic amd64 Java 1.8.0_201 The error message no longer appears. Thanks! The copying to the clipboard works fine when done by right-clicking the item in the table and working off the popup menu. But it does not work when using the main Edit / Copy ... menu.

[Siedlerchr]

The edit menu thing can convert it to HTML (default) XML or rtf. But somehow the options are missing from the menu
I will investigate this tomorrow
