I have an application that currently runs under Tomcat 4.1 JDK 1.4.2. Recently, I installed JDK 5.0 on my machine, set the Compiler compliance level to 1.4 (in Eclipse) and allowed all source files to rebuild. The application still seems to run fine under Tomcat 4.1 JDK 1.4.2 with one exception. I have one dialog that fails with the following exception message.
Questions: 1) Is this a known problem? 2) Should I even be attempting to run code compiled using the 5.0 compiler (at 1.4 compliance level) in a 1.4 JVM? Note that I am only attempting to do so in my development environment.
