Junit5's #CsvFileSource annotation not working with Eclipse - java

I'm running a set of tests with Junit 5.
They work correctly if they are launched by Maven, but I cannot run them properly in Eclipse.
Apparently the problem is that Eclipse does not consider correctly the parameters of the annotation #CsvFileSource.
Test:
#ParameterizedTest
#CsvFileSource(resources = INPUT_FILE_NAME, numLinesToSkip=1, delimiter=';')
public void testSpot(
String crossCcy,
#ConvertWith(LocalDateConverter.class) LocalDate date,
#ConvertWith(LocalDateConverter.class) LocalDate expectedSpot
) throws JFxLibException, IOException {
FxDateCalculator calculator = FxDateCalculator.newInstance(crossCcy);
LocalDate spotDate = calculator.getSpotDate(date);
Assertions.assertEquals(expectedSpot, spotDate, "Cross " + crossCcy + ", date=" + date + ",");
}
Mvn:
$ mvn test

I'm using Eclipse Oxygen:
Version: Oxygen.3a Release (4.7.3a)
Build id: 20180405-1200

Ok, solved.
Eclipse Oxygen uses by default org.junit.jupiter.api_5.0.0, which does not contain numLinesToSkip parameter in CsvFileSource annotation.
My Maven dependency had version 5.1.0, which contains this parameter. That's why it worked properly. Upgrading Eclipse to 2018-12 (org.junit.jupiter.api_5.3.1) made the deal for me.

security: blacklist: hasBeenModifiedSince 0 (we have 1474524668053)
But with JRE7.08 it is running fine. After installing JDK8 it's not running. What was the problem ? Do i need to change any settings. Please help me.
I have found solution for this i.e., configured invalid proxy settings in
Control Panel --> Java --> General --> Network settings and those are differ with browser settings. So, selected Use browser Settings and tried again them it's working fine.

ILazyInitProxy ClassNotFoundException in Wicket Websocket

The AbstractWebSocketProcessor class tries to broadcast a message to notify listeners that the websocket closes.
In doing this, it tries to load a wicket page. That page contains multiple autowired fields and it needs to be deserialized, but that's where the classnotfoundexception of the proxy class occurs.
I suspect this issue to be the cause of a thread leak, but I can not reproduce the error consistently.
How could this error occur?

Jenkins is failed to checkout source from Subversion

Hi All please do not put this question as a duplicate since I checked all the question for an answer before posting it.
My Question is this:

Finished: FAILURE
by mistake my team checked in .class files after removing the .class files from repository it is now working fine.
Try the following:
1)Change your svn configuration to 'allow from all' on the httpd.config. So something like this if using apache 2.2
<Directory /repos>
...
allow from all
...
</Directory>
Or if using apache 2.4
<Directory /repos>
...
allow from all
...
</Directory>
2)Clean up the project i.e. SVN->Working Copy->Cleanup (if you are using netbeans)
3) Ensure you have enough disk space

SWT TreeViewer Drag n Drop: SWTException Widget is disposed

I have a CTabFolder containing a few disposable tabs which contain a TreeViewer each. I want every Viewer to have a DragSupport. So naturally i used the method TreeViewer#addDragSupport for that. Everything works as expected, except when i close the shell and SWT tries to dispose all the widgets.
The Exception that occurs is:

which seems a bit extensive. It seems that SWT tries to remove the DragListener from the Tree after it had been disposed. I dont really understand how this is even possible.
I dont think that i made a mistake implementing the Source/Target and the Transfer type, since the dragging and dropping works like a charm.
Are there maybe any pitfalls to consider when adding a Drag Support to a TreeViewer which is contained in a disposable Widget?
If you need a Code example let me know.
It shouldn't bee a problem. You have 2 options: write a piece of code that gives you that error or just add a dispose listener event on the Folder and remove the drag support there.
