Version of Java: java version "1.6.0_27"
OpenJDK Runtime Environment (IcedTea6 1.12.5) (6b27-1.12.5-2)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)
Operating System: Debian Testing AMD64

What steps will reproduce the problem?
1. Download oo2gd_3.0.0.oxt
2. Start LO
3. Open "Tools - Extension Manager" and click on "Add..."
4. Browse to your downloaded extension
5. Click on it
6. Click on "Only for me" in the next dialog
What is the expected output? What do you see instead?
No error message, but an installed extension ... ;) Instead you get an error 
message: java.lang.reflect.InvocationTargetException ...And an (corruptly 
installed) inactive extension isn't useful at all :(
Please provide any additional information below.
Please don't ask me to install my distro's version of LO :) I am involved in 
LO's QA/translation, so I prefer the upstream version of LO :)
Sorry for the inconvenience
Thomas.

ooo2gd_3.0.0.oxt activation fails under Xp/32 if  LanguageTool-2.1.oxt is 
installed. After uninstall of LanguageTool ooo2gd works fine.
L.O. vers.:4.1.0.0.4, XP/32 sp3

Hello Willi, *,
thanks for your tip. This works :) But I still think, it is a bug, as I can 
install other extensions, although the LanguageTool extension is installed ... 
;)
Thanks again
Thomas.

I have exactly the same problem on Ubuntu 14.04 and I have no other extensions 
installed

For Ubuntu 14.04 you can try this:
1)After installing Java, open LibreOffice>Tools>Options>Advanced>Select JRE to 
Use.
2)Close Libre Office
3)Then install libreoffice-java-common using sudo apt-get install 
libreoffice-java-common
4)Now start LibreOffice and Enable the extension. 
5)Plugin should work now.
