Re: [xmlvm-users] General questions wrt. Java iPhone development with XMLVM

[Arno P. <ar...@pu...>]

what Panayotis meant to say is that the C backend is not yet ready for 
prime time, so we suggest you use the Objective-C backend for now. Once 
the C backend is the default, it will be more complete than the 
Objective-C counterpart. The C backend (already today) can cross-compile 
Apache Harmony (a J2SE implementation). The Objective-C backend cannot 
do this because it can't handle certain kinds of polymorphisms in Java. 
You can take a look at src/test/PolymorphismTest that cannot be compiled 
by the Objective-C backend. Then we have integrated a full Garbage 
Collector in the C backend. The Objective-C backend still relies on 
reference counting and it happens *very* quickly that your application 
contains a cycle in the data structure and therefore leaks memory. These 
are just two things where the new backend is superior.

We are making good progress with the C backend. All of our internal 
iPhone demos almost work. Next we make the Android Compat Lib 
cross-compile with the C backend. Once that works, we are ready to 
switch to the new backend.
