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

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

What version of the product are you using? On what operating system?
Talend Open Studio 4.0 and OS Windows XP sp3.

Please provide any additional information below.

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
