Oxygen XML Forum

Hi,
we are integrating the OxygenXMLAuthor Eclipse Plugin v24.0 in an Eclipse RCP Application.

When the Eclipse RCP Application gets closed, the org.eclipse.swt.Display will disposed.
This leads to a Nullpointer-Exception in the OxygenXMLAuthor that pops up when closing the Application:

Here is an excerpt of the Stacktrace:

java.lang.NullPointerException
at com.oxygenxml.editor.EditorPlugin$31.run(Unknown Source)
at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:40)
at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:185)
at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:4029)
at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3629)
at org.eclipse.swt.widgets.Display.release(Display.java:3704)
at org.eclipse.swt.graphics.Device.dispose(Device.java:324)
.....

Do you have any advice how to avoid the occurance of this NPE ? May there be a possible Bug / missing nullcheck?

Kind Regards

Hello Steve,

Can you please specify also the Eclipse distribution and build number ?
The problem you encountered is also available in the 24.1 version ?
We strongly encourage you to use the 24.1 version since it usually contains not only improvements but also bug-fixes...
I will try to reproduce the problem on our side as well.

Regards,
Mircea

Hi Mircea,

thank you for your reply.
The Version of the Eclipse RCP Platform used is 4.21.

The org.eclipse.swt Plugin has the Version 3.117.0.v20210906-0842

Hi Steve,

Have you tried the 24.1 version as suggested ?

Regards,
Mircea

Hi Mircea,
sorry for my late Reply.

I used the 24.1 Plugin as you suggested and did some testing and it seems that the NPE does not occur anymore.
