What is the minimum version of Java that is necessary to run the HDF5
Java libraries? Is it 1.6, 1.5, 1.4...? The prebuilt JAR files available
here (http://www.hdfgroup.org/ftp/HDF5/hdf-java/bin) have been produced
with a compiler yielding JRE 1.6 output. If 1.6 is not necessary, could
someone from hdfgroup.org please consider recompiling with the "-target
1.5" flag set (or 1.4 or earlier if that works; it doesn't look like
you're using features from recent JREs) so that the JAR files are
compatible with JRE 1.5? This seems to be standard practice for
publishing JAR files: for example, the latest release of GlazedLists
1.8.0 is compatible with JRE 1.5, and Apache Commons Collections 3.2.1
is compatible all the way back to JRE 1.2.
Otherwise it forces people to use JRE 1.6 or try to recompile the source
code for earlier JRE versions. (We're running MATLAB R2006a on most of
our computers here and it uses JRE 1.5)

The minimum is jdk 1.5. I did not use the "-target" flag.
There may be a performance issue to use JVM 5
classes. I want to take the advantage of JVM 6 performance.
However, I will use" -source" in the future release to make
the source compatible to version 5. You should be able to
use jdk 1.5 to build your application.
Thanks
