I just found the problem, and it was in my own source:
My copy function did the following:

List<Variable> variables = ncIn.getRootGroup().getVariables();
for (Variable var : variables) {
   // copy dims and attributes
   ncOut.addVariable(ncOut.getRootGroup(), var);
}

ncOut.create();

for (Variable var : variables) {
   try {
      ncOut.write(var.getName(), var.read());
   } catch (InvalidRangeException ire) {
      throw new IOException(ire.toString());
   }
}
ncOut.flush();



The line 'ncOut.addVariable(ncOut.getRootGroup(), var)' modified the
variable which got read afterwards. Modifying this line to
              Variable outVar = new Variable(var);
              ncOut.getRootGroup().addVariable(outVar);
solved the problem.

Sorry for bothering you with a self-generated error.

Best regards

No problem.

You may want to look at or use ucar.nc2.FileWriter.java for these purposes.
