Cisco ASA ASDM unable to launch device manager

After upgrading to Java version 7 update 51 (build 1.7.0_51-b13) I encounter an error, among a lot of other problems and errors!, which I couldn't use the ASDM (7.1.5) to login into my ASA appliance.

Apparently there is some  compatibility issues between the Java and the ASDM, according to Cisco there are two possible solutions:

1. Use the ASDM Java web start to launch the ASDM (note that first you will have to install
Jave JRE (link: http://www.oracle.com/technetwork/java/javase/downloads/jre7-downloads-1880261.html)

2. Downgrade Java from 7 update 51 to 7 update 40, you can find it here:
