Yes, jamvm and gij-4.0.

I don't want block JVMs they are not in Debian, because the Debian ones
are not fully functional. So I don't want to write "kaffe | sablevm |
jamvm | gij" in the Dependens line, but than I get the problem of
allowing old JVMs or JVMs I don't know.

What would be a better way? I think you get the same problem, if you
force to use a C99 compiler. gcc may provide this, but other c compilers
not. What would you write in the Dependens line if you need a c99. And
the problem for me with java is, all JVMs in Java do not work fully with
my package. Only the JVM from SUN gives you the whole functionality.

Bye, Jörg.
