I tested the SpreadSheet's spreadsheet file support (the "Setup" menu)
on both Windows NT and Solaris, and I didn't encounter any problems.
The saved files loaded fine, including the data mappings.

If you are encountering this error with a specific data file, please
send me the file if possible so that I can track down the problem.
If the error occurs with all your data sets, then make sure you have
the latest release of VisAD.

ScalarVector is a static field of the ScalarType class that contains
a list of all ScalarTypes created so far in that JVM.  It is
initialized and added to as ScalarType objects are created.
