However, Groovy is also very popular amongst JBossians. We also have many expression languages that we love. jBPM, Seam and Rules all have different ones. For the first version of this feature, I'm of the opinion that we should keep it simple. I'm personally happy with Groovy and Beanshell only. I'm also happy with using the Java 6 scripting capability but I don't believe we've tested the overall ESB with Java 6.
