Description

There is a JNI-based impemlemtation here: http://www.hdfgroup.org/hdf-java-html/hdf-object/index.html, but I'd rather not use it if there's a pure java implementation. This is what Saddle uses, though.

Quick googling suggests there's no pure java implementation.

Contributor guide

Research direction
Research pure Java implementations of HDF4/5. If none exist, evaluate the feasibility of creating a JNI based wrapper using the existing reference implementation.
