UnsupportedClassVersionError

[GoogleCodeExporter]

What steps will reproduce the problem?

1. I have installed the 1.5.0_09 version JDK in Talend Open Studio, then when I 
run the job I'm getting the message:

java.lang.UnsupportedClassVersionError: Bad version number in .class file

    at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)

I tried out with jdk 1.6.0_17 and I'm getting the same message.

Hello valekas,

currently JAR files are compiled for Java6 with Java6 support. We would 
recompile them with -source 5 however for a quick fix you can also do it on 
your own, just check out sources and run the build with Java5
