Do you have a preference for either of them ?
No, it doesn't matter. Pointer is probably more in line with the rest
of the source code. As far as the compiler is concerned, they're the
same thing.
There is however some functionality (e.g. writestr with ansistring)
that uses the UserData byte array to store a pointer, which won't
work on the JVM target. Some extra classes will also have to be
moved from the jdk15 unit to the system unit to implement the
functionality.
That brings me to my second question/remark: (which I had already
prepared before sending my first mail ;) ):
It would be easier if the system unit could depend on jdk15 in the
implementation section.
However, this is something that FPC never has been able to do, while
Delphi can. It would be good if FPC could do the same, it would make
some system units easier to manage. (in casu: the Java one)
Well, in that case we could just get rid of the jdk15 unit altogether
and put everything directly in the system unit. The main reason I
didn't do that is because it makes loading the system unit slower due
to the tons of definitions (otoh, most "real" programs will probably
use the jdk15 unit one way or another anyway). It's true that the
downside is that occasionally definitions have to be moved from the
jdk15 unit to the system unit.
