Papyrus: Error exporting diagram as an image file - eclipse

This problem refers to an Eclipse Kepler instance running on Ubuntu 12.04. I have a Use Case diagram that I need to include in a document as an image file. I right click on the .di file, select Export All Diagrams... and then select PDF as the file format. In return I get an error window with the following:
ExportAll report
Reason:
Generation failed for some tests
In the error log an exception is filed:
Message:

What is wrong here? How can I export the diagram as an image file? Thanks.

I found that some elements (like Actors, ReceiveSignal) didn't accept a negative value for the Line width field. On these elements, you can replace the "-1" value by "1" in Properties / Appearance / Line width field.
Hope it helps...

Export it as an SVG file. You can view them in a browser and convert them to other formats later

Somewhere, I read that 6.3.1 version contains extra attribute than 6.2.2 version. At initially I use 6.3.1 but later on I changed it to 6.2.2 but whenever I try to remove "uuid" attributes from the jrxml components, it automatically back when file saved.
What is the issue exactly, what should I do ? Please anyone help me from this jasper reporting!!!!!
:(
The error is caused by a JasperReports style template (*.jrtx file) that you use in your report.
Prior to 6.3.0, style templates used a DTD:
<!DOCTYPE jasperTemplate
PUBLIC "-//JasperReports//DTD Template//EN"
"http://jasperreports.sourceforge.net/dtds/jaspertemplate.dtd">
Starting with 6.3.0, the templates use an XML schema (but the DTD is still supported for backward compatibility):
<jasperTemplate xmlns="http://jasperreports.sourceforge.net/jasperreports/template" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/template http://jasperreports.sourceforge.net/xsd/jaspertemplate.xsd">
The problem in your case seems to be that you are using a 6.3.0 style template in JasperReports 6.2.2. Which will not work, make sure that your *.jrtx file has a DOCTYPE and no xmlns and xsi:schemaLocation attributes.

Eclipse error in project properties

I have Eclipse installed on my Antergos (Archlinux-based) operating system and I wanted to change settings in the C/C++ build of my project but when I try to open that I get the following error:
.
This error is followed by a Java exception (NullPointerException).
I tried updating the Eclipse but it is already up to date. I also tried to restart the application and clean/build but to no avail.
Until today I never had such a problem with it. I thought maybe it is a new update but I couldn't find someone else who had experienced the same problem.
What does this error mean and how to fix it?

I think Archlinux users seems to be the first to see it due to the fact Arch packages are always at the latest version available and have recently updated Gtk and Wayland libraries.

Unexpected Null pointer causing rcp theme lookweird

Suddenly the theme is getting a null pointer exception here is the stack trace has anyone seen such issue and resolved it. I am assuming some kind of race condition is occuring but I have not been able to pinpoint the cause.

adding -clean flag to run-time configuration solves the issue but still no idea what is causing it. so I will appreciate a solution that a temporary fix
Add it to Run/ Run-Configuration/Arguments
-os ${target.os} -ws ${target.ws} -arch ${target.arch} -nl ${target.nl} -consoleLog -clean
First and foremost, It's a known Bug in Eclipse Bug 440763. It has something to do with the Eclipse version, since in 4.3 I wasn't facing the exception. It looks like a regression problem of the CSS-engine in Eclipse 4.4.
I don't know exactly what's the problem in there, but here is how I got rid of it.
Removing this plugin org.eclipse.ui.themes from dependencies (and from the target platform) solved the problem.
Go to Run Configurations -> Arguments -> Program arguments
Add -clearPersistedState
I guess, this wouldn't qualify as a response since I don't give any explanations, but it sure helps.
Go to C:\Users\USER\eclipse\ECLIPSE_VERSION\eclipse\configuration\config.ini
Open file config.ini
Add this line: osgi.clean=true
Start eclipse.
If it is working then delete this line afterwards.
This is same as -clean argument.

You probably switched Perspective. Go to Window -> Open Perspective -> Other and choose Map/Reduce. This should also bring you back DFS Locations.

Android Eclipse won't start. An error has occurred. see the log file

I know that this question has been asked several times on StackOverflow (and others), but none of the solutions I've found works for me.
As you can see in the headline I am getting the following error message, when starting Android eclipse:
an error has occurred. see the log file
I have tried removing SNAP files and Vmargs directive from the eclipse.ini file. I've also tried to clean Eclipse with the command:
PATH/TO/ECLIPSE -clean
But with no result.
I am running the ADT Eclipse bundle on Windows 7.
And here is what my log file says (repeatedly) when I try to run it:

I really hope some of you can help me fix this.
The last time I closed Android eclipse, some problems occured because it was out of memory. I don't why this suddenly happened.
Of course, just after posting the question, I've found the solution.
If others run into the same problem, try deleting the following folder from your workspace:
C:\.. \workspace\.metadata\.plugins\org.eclipse.e4.workbench
