Hi!

sorry for the delay. I tried your patch, but the build fails for me
because it goes "out of file descriptors" and "unix resources". Does it
work for you? I tried with various levels of parallelism, but it did not
change anything.

also about your patch, could you replace (invoke "chmod" "u+w" file)
with a call to make-writable? It's available by default in the build
environment, it comes from (guix build utils). I wonder also why you
inherit arguments from openjdk15 instead of openjdk16?

Thanks!
