With the patch I submitted earlier today, I tried to set the
#:validate-runpath? to #t, but the build failed.

It seems there are more libraries with linking errors:
$ ldd /gnu/store/fy8krxbj60z9kx9hwsp4f08qjgr2cb20-icedtea-2.6.11/lib/amd64/xawt/libmawt.so
        linux-vdso.so.1 (0x00007ffc94ed3000)
        ...
        libawt.so => not found
        libjava.so => not found
        libjvm.so => not found
        ...

So, again libjvm.so, because this is in different directory.
libmawt.so is used by libjawt.so, (and libjawt.so cannot find libmawt.so
either).

So there's definitely more to investigate/fix here.

Nevertheless, my immediate need is to fix that libjvm.so linkage error
from libjvm.so.  So I would like to go ahead with the patch I submitted
earlier.

I am investigating the remaining linkage errors and whether there's a
better fix than creating symbolic links.

Kind regards,
