My default jre for eclipse and projects is jre1.5.0_06. For a particular project, I am asked to ensure that it works on java 1.4. It's not enough to set the compiler to 1.4 compliance, I must also not use classes and features that were introduced in Java 5. According to the information in bug 40098:

> It is far simply for you to manually to simply switch your JRE setting
> for the project match your expectation (see installed JREs preferences,
> and add the ones you care about)

This works fine, but isn't practical when sharing projects between developers - because it's done by jre name, and our jre names may not match. So then they report bugs because the build path doesn't work, and we argue about jre sub versions. Can we have a solution to this problem? 

it seems most appropriate to add a new feature allowing jre's to be associated with the compiler compliance level, so that we can say, this project has compliance for 1.4 and also uses the 1.4 jre - whichever one of them you have chosen or are required to use.
