I'm rather unfamiliar with Ada, so I won't discuss it.

C++, of course, does support OO.  It ain't a PURE OO language--it
owes much to C, which is a structural langauge, and the current
library promotes generic programming much more than true OO programming.
Also, there are lotsa pitfalls to avoid, and if ya need distributed
objects, C++ alone won't cut it.  (CORBA, anyone?) But for closed-system
OO that is efficient and well-supported, C++ does quite well.

Java is a more "pure" OO language.  Since your laundry list :) missed
the programming paradigm most fashionable these days--component
programming--Java provides better native support for this than does
C++.  

> > - support parallel programming

How do you mean?  All of 'em, if ya use a multithreading OS on a 
multiprocessing machine, with appropriate libraries, can be used to
write code that can run on multiple processors.  The partitioning you
get this way is course-grained (threads, essentially), and you got
to do the partitioning yourself, but it works.  Java has threading built
in to the native library; C and C++ require you to use OS libraries
to achieve multithreading.

Or were you looking for something where you can specify an algorithm
and the compiler will automagically partition it among processors?  
If you are doing heavy-duty number crunching, the language you probably
want is Fortran (or FORTRAN) :).  If you are mainly doing control 
and/or UI tasks, fine-grained parallelism ain't gonna buy you much of
anything.

> > - lead to easily maintainable code

This depends as much on the competence of your engineering staff. 
However, Java has the advantage of a binary interface standard, where
C and C++ do not.  Generally, the output of different C compilers can
be linked together without problems; this is NOT true for different
C++ compilers.


> > - promote safe programming techniques

Java does this in spades--in fact, many reasonable-but-possibly-abused
techniques are banned in Java.  Not becuase Sun thinks programmers are
idiots, of course, but because this is a requirement to support Java's
security model.

C and C++, on the other hand, will gladly allow you to shoot yourself
in the foot.  Safe code can be written in 'em, but so can dangerous
code.

In the vxWorks space, C/C++ are the clear winners here.  Diab data,
Green Hills, Metroworks, and Cygnus/FSF all provide C/C++ compilers that
target vxWorks.

Java ports to vxWorks are much more limited--and not as mature as their
PC/workstation counterparts.

GUI libraries are another issue altogether.  Given that vxWorks is
deployed, most of the time, in environments without a GUI, this is
a major weakness--for either language.  Wind River/Zinc has a few
solutions (RtX-Windows, UGL), none of 'em are particularly great.  

All the AWT implementations I've seen targeting vxWorks rely on one 
of the above libraries.

> > - be available for popular processors (such as 68xxx, PowerPC, etc.)

C/C++ compilers are available for all of the above.

PowerPC java virtual machines are available from various sources, 68k
ones are probably harder to find.

> > - enjoy wealth of existing solutions

Solutions to do what?  

> > - support "almost real time" execution

Either you are real time, or ya ain't.  C and C++ can certainly be used 
to write deterministic code; though the lack of formalization of these
means that you'll have a lot of testing to do to prove it.

Java is currently worthless for real-time; because of the garbage
collector.  I've heard stories about supposed real-time garbage
collectors (which don't block other threads from running, or do so
for a bounded amount of time)--but you still have to prove that you
never run out of memory if you do that.  With Java, you CANNOT create
objects on the stack--so there is no way of avoiding dynamic memory
allocation.

> > - be suitable for design of embedded systems

C and C++ certainly are.

Java may be, depending on how deeply embeeded you are talking about.
Given that you have mentioned things such as GUI support, and have
asked about processors such as powerPc, it sounds like you will have
some CPU horsepower and memory at your disposal.  Including a JVM,
an implementation of the Java library, and an underlying GUI library
is going to add about 2-3 Mb to your program size, and that's an 
efficient (but full) implementation.  Things like PersonalJava or 
EmbeddedJava reduce this figure, but you will still need a bunch of 
memory.

Much more than you will for a C/C++ implementation.

> > - have existing support for vxworks

I've been assuming vxWorks throughout the document...see above for 
my comments.

Agreed.  Much of the above seems to be a list of buzzwords...do they
really correspond to product requirements?  

What is it you are trying to build, if I may ask????
