I've tried John's suggestion and it helps but is not enough. I believe I would
have to trap the outer make invocation as well. Unfortunately wrapping make in
a script just to be able to to use ctrl-\ is probably not worth it.
If what you need to wrap make is something like
#!/bin/bash
sh -c "trap '' QUIT; make "$@"
and that, combined with the patch below, does help you achieve what you
want, maybe you can create a common/bin/make_wrapper.sh with that code?
That way, the wrapper is there if you need it, otherwise you can ignore it.

I'm instead using jstack though it can be harder to get timing right.

I don't see how make and all the intervening shells could know to pass the
signal through to the JVM process. ??
IIRC they don't need to pass the signal, because the signal goes from the tty to the current group of
processes. A waiting shell or make probably disregards such signals and pays more attention to the response
to the thing it is waiting for. In this case, perhaps the "tee" command gets sick from the signal
and causes the pipeline to fail. Perhaps the "tee" command needs to be wrapped in some kind of
trappy thing like: sh -c 'trap "" 2 3; tee'
