Sascha, I think when you are building a platform it is OK to dictate a minimum Java version of say 1.5 as people can have multiple VM's installed on their machine so can support both 1.4 and 1.5 apps.
If you are developing a library which is designed to work in say a web application server or a general library such as JTS then you would want to ensure you reach a wide code base,for example my client uses an old version OC4j which only runs on JDK1.4 so I have to develop all my apps for that.
