In terms of my original point, yes, rotd-2013-10-01 has mfilterjavac
disabled
by default -- you need an rotd that would attempt to use it by default.

Also my original step should be:

   cd stage2 && make install

(i.e. not mmake).  Note that for none of this do I have a Mercury
installation
in my PATH.

Since I wrote the above, I wonder whether the above was intended to work --
at the moment it does work, with the exception of for the java grade with
mfilterjavac
enabled.  In particular, the compiler has no trouble finding mfiltercc at
this point, which
leads me to suspect your original change that introduced mfilterjavac left
something
out of a M(m)akefile somewhere.

I'm using a workspace based on the current master with mfilterjavac

I think you have misunderstood; it is rote-2013-04-18 I am bootchecking
above,
not a separate workspace.

Cheers,
Julien.
