1. cdm/pom.xml - cdm appears to depend now on sleepycat;
                 added the dependency
2. com/sun/jna/MyPointer - newest version of jna obviates
                           the need for this, so deleted.
3. ucar/nc2/jni/netcdf/Nc4Iosp - changed all references of
                                 MyPointer to Pointer.
