About eclipse startup error in Ubuntu 12.04 LTS

After re-install Ubuntu 12.04 some-days ago it seems net and clean OS to me. When I first time using Ubuntu for long 6/7 months it was full of my errors of install software or mis-configure some issues. But this time I am aware of that so I feel comfortable with this and not mess-up anything. But today when i tried to install eclipse from software center then I found an error as follows,

An error has occurred. See the log file /home/tapan/.eclipse/org.eclipse.platform_3.7.0_155965261/configuration/1335382319394.log .

And I checked the log file which says something like follows,

and so on….

I tried to re-install the software but it was same. Then I google this issues and came to know that if i use open jdk then it will be ok. But I was not wiling to install open jdk when I have oracle jdk 1.7
so after google for some workaround and I found to know that if I copy all the files from /usr/lib/jni to ~/.swt/lib/linux/x86 then it would be fine. So i did as follows,

sudo cp /usr/lib/jni/libswt-*3740.so ~/.swt/lib/linux/x86/

And now I can run eclipse smoothly.
