javacomp.m4 already tests whether javac is functional by calling

    javac -version >/dev/null 2>/dev/null

and seeing whether the exit code is 0, 1 or 2. If your placeholder is
nonfunctional, let it return a different exit code, such as 125. Or move
it away entirely from your */bin directories.

Maybe you could please post the source of this placeholder, so I can make
up an autoconf test against it?

This will work, yes.

gcj -C has problems of its own. I don't recommend this workaround.
