jikes is compatable with JLS 1.1 (or is it 1.0 ???). It is the most
compliant compiler out there. (JLS == Java language specification).
microsofts jvc is the least compatable while suns javac is in between ;)

nope - it accepts a superset of features

it more has to do with allowed language constructs. jvc allows too much and
tries to optimize too much. Stuff compiled with jvc will not work on
1.2/1.3 vms (the same with stuff compiled with 1.1 javac will not work on
1.2/1.3 vms).

what version jvm are you using on linux ?
