Re: JDK/JRE and older Java versions

Peter, I apologise for giving you tangential (and unsolicited) advice instead of helping you with your problem, however :) Have you tried Docker? As a developer myself, I find Docker to be invaluable. Basically, you can create an isolated environment with any toolchain in one command. This would let you test your code under practically any JDK or JRE without "polluting" your actual desktop system. Sorry again, especially if this is something you've already considered. Best regards, -- Edward
