The problem is related to the fact that the lpCommandLine argument in the
win32 CreateProcess() is limited to 32Kb. Therefore, you can never have a
commandline invokation that exceeds 32 Kb.

Your namespaces probably consist of several sub-namespaces, if you have 850
.class files:

com/mindark/*.class 			<--- split
com/mindark/script/*.class		<--- split

My advice is to use the ar utility to group the .o files  for each
sub-namespace into their own .a files:

ar -cr archive/mynamespace.a myobject1.o myobject2.o myobject2.o ...

Make sure to limit the number of .o files to a few hundred. With Ant, you
can do the following:

  <target name="archive">
        <apply failonerror="true" executable="ar" parallel="true">
            <fileset dir="obj/com/mindark/firstnamespace"
includes="**/*.o"/>
            <arg line="-cr arc/firstnamespace.a"/>
       </apply>
    </target>


You will end up with a manageable number of .a files. Next, you can link all
.a files into the target required.
