We provide a popular open source Java FTP library called edtFTPj. We would like to drop support for JRE 1.3 - this would clean up the code base and also allow us to more easily use JRE 1.4 features (without resorting to reflection etc). The JRE 1.3 is over 7 years old now! Is anyone still using JRE 1.3 out there? Is anyone aware of any...
