UnsupportedClassVersionError indicates, that you try to execute a new class (i.e.: 1.6) with an old jre (i.e.: 1.5).

Different subversions (1.4.2 to 1.4.1) don't count here.

It's a typical occurence, if you OS has a preinstalled JRE to run java-programs, and you later install the JDK.

which java

tells you on a linux system, which java is used (i.e.: /usr/local/bin/java).
