If a user uses oracle java 7 (currently in a webupd8 ppa) and tries to load eclipse, an error similar to that below occurs (as described here http://stackoverflow.com/questions/10165693/ubuntu-eclipse-cannot-load-swt-libraries-not-opening)
The problem is that the SWT libraries are not located in "/usr/.swt/lib/linux/x86_64/" but in "/usr/lib/jni/" and eclipse doesn't look for them hard enough, and then complains it can't find them.
The workaround is to create a symbolic link
(for 32 bit)
ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86/
And on 64 bit:
ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/
or to use "sudo update-alternatives --config java" and select to use the openjdk version.
