This is a bit of a strange question - please bear with me.
I have set my hands on an old Windows CE palmtop which happens to run JRE 1.5 (certain, and possibly JRE 1.6).
I was wondering if I could develop a simple Processing sketch that would run on this version of Java.
I know current Processing sketches (as exported from the latest 3.5.3) can run using JRE 1.8.0_74.
Should I try developing with an earlier version of Processing? If so, which one? Or, can I rebuild the Processing libraries with J2SE 1.6 (since they only use the syntax for that version) and then manually compile my Processing 3 sketch?
Many thanks in advance,
