Yes (once THandle is added to the JVM RTL and it is defined to Pointer or
JLObject, at least :). It's generally a PrintStream:

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.
I had hoped for this :-)
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.
From a maintenance point of view, I think it is better if they stay in a
separate unit.
As long as the system unit cannot handle separate units we can maybe make
a jdk15sys.inc, and include this in jdk15.pp and in the implementation
section of system.
