We (Oracle Java Platform Group) can handle the required "paperwork" on any third party dependencies and attribution of copyright before any PR can be integrated, if you can help detail what those are. First i think we need to determine if this is feasible e.g., copying a subset and integrating it into the build system, since it does not make sense to bring in the support for quad floats and DFT, which IIUC brings in a dependency on compiler support for OpenMP.
