I couldn't find a way to address this error, so I would appreciate some help here :) Perhaps @floidgilbert could shed some light here, please?

This is how our depencies look like in our DESCRIPTION file.

I haven't encountered that error. A quick Google search shows that it is a common error on CRAN and there appears to be many possible causes. I suggest contacting the folks @ CRAN for suggestions. It's interesting that it fails only on Solaris.

Uwe confirmed to me that the Solaris server does not have Java Runtime Environment (>= 8). I asked whether this error on Solaris alone should be a problem to keep the package on CRAN. Here is his response:

Ideally move the jdx dependency to "Suggests" if that nmakes sense and
you have funtionality that does not strictly depend on jdx in order to
make your package available on more platforms. If you need it strictly,
that's OK, too.

Best,
Uwe Ligges

Our package does depend on jdx so we are keeping it under Imports. I guess this shouldn't be a big issue. Closing this issue for now.
