How downwards compatible is JRE?
I noticed there's a new JRE in town, the upgrade 20, I still use the 13. What will the up to 20 do for the software I write? I use openJDK (came with the Fedora I use) to write software, and the JRE to use it in the browser, I needed to see the Java console, hence the need for the Sun JRE...
So: bottomline: if I upgrade to the new JRE - use the alternatives configurator to use that in the browser, will the software written in the current JDK (1.6) still work? Or: is Java downward compatible?
Tnx for an answer!
PS : I dont use anything fancy, just RMI, mySQL connectivity and a bit of Swing...
