Eclipse won't start on Linux "Could not load SWT library" with Oracle Java 7

Problem:
When starting Eclipse on Linux (64bit Ubuntu 12.04) you get an error message:
An error has occurred.  See the log file
/home/<user_name>/.eclipse/org.eclipse.platform_3.70_155965261/configuration/1335552227148.log.

Opening the log file reveals the following:

Solution:
Execute the following command to create a symlink to the current version of swt:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/
