I noticed that the build.xml in OpenJump/etc does not specify source and
target java versions. I don't know what the defaults are. Here is the
line from the build file:
<javac srcdir="${src.dir}"
destdir="${build.classes}"
debug="${debug}" //this is off
deprecation="${deprecation}" //this is off
optimize="${optimize}">
<classpath refid="base.classpath"/>
In SkyJUMP I explicitly specify that both source and target be 1.5.
SkyJUMP's build uses:
<javac srcdir="${src}"
destdir="${build}"
classpathref="buildpath"
deprecation="off"
debug="off"
optimize="on"
source="1.5"
target="1.5"
nowarn="off"/>
You can then run the executable on 1.5 and 1.6 but not 1.4. Note that under
Eclipse "project - properties - Java Compiler" there are three settings:
Compiler Compliance level, Source compatiblity, and Generated .class files
compatibility. I have all of these set to 5.0. I get some errors now if I
don't set for 5.0.
I run and build under 1.6 now, but sometimes test under 1.5 for comparison.
1.6 is much faster than 1.5.

I would recommend for now that we stick with 1.5 for the core, plug-ins
can be free to do whatever they want I guess.
I did notice however that running under 1.6 or even 1.5 is a lot faster
than 1.4
