I downloaded a software sometime back and when I ran it I got the following error:

Exception in thread "main" java.lang.UnsupportedClassVersionError: <Class Name> (Unsupported major.minor version 48.0)
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(Unknown Source)

at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClassInternal(Unknown Source)

This happened since my default java version is 1.3 and not 1.4 - which was the version that the above application required.

Wouldn't it be nice if one could capture this in the application and display a better message to the user - stating "You need JDK Version x.y" to run this application?
