Timestamp: "Today" and "None" not clickable

[mlep]

JabRef version 3.6 on Linux Mint LMDE

In the entry editor, right next to the timestamp field, an icon triggers the pop-up of a calendar.
Under the calendar, today and none are displayed:

I believe these were clickable (to input today's date, or to clear the field).

Yes. They are clickable on Windows...

@mlep: Which JRE are you using?

[mlep]

java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)

[lenhard]

@mlep: Thanks! Is this OpenJDK or Oracle?

[matthiasgeiger]

I think this output is generated by Oracle ;-)

[mlep]

I confirm: Oracle

[lenhard]

@matthiasgeiger As far as I know, that output is also generated by OpenJDK? But maybe this has changed. How should the output by OpenJDK look like?

Back to topic: Darn, I was hoping we could blame this on OpenJDK...

Tested under Ubuntu 16.04 with Xfce Desktop and oracle jre
Also it says it's javax.swing.plaf.metal.MetalLookAndFeel, it should be GTk looks.

They are clickable, and clicking on today works correctly. Clicking on none does nothing

[mlep]

Checking again:
Correction: only click on none does nothing.
Like @Siedlerchr, using javax.swing.plaf.metal.MetalLookAndFeel

[matthiasgeiger]

Mhmm okay. "none" is also not working as it is to be expected in windows: It closes the Calendar, but a date previously set is not removed.
