RE: wrong version 49.0
Hi, If you compile your classes with J2SE 5.0 (class version 49.0), you can't run them on JDK 1.4.2 (class version 48.0). Either match up the compile- and run-time JDK version, or compile with a -target switch to match the older JDK.

RE: wrong version 49.0
Thanks Yoav. That is what I guess. I, however, can't find what I can change the JVM version in the TC configuration. If you compile your classes with J2SE 5.0 (class version 49.0), you can't run them on JDK 1.4.2 (class version 48.0). Either match up the compile- and run-time JDK version, or compile with a -target switch to match the older JDK.
