com-jaspersoft-ireport.jar missing JRXmlWriter classes

These old versions are no longer supported. The internals of JR have been changed too much to be able to support them. We decided to write custom writers for a few versions back, but it does not make sense in newer versions to support stuff in an uncertain way (I say uncertain because, since the class attribute has been removed from classes, it would work only by modifying an old report, but save to old versions may produce errors with newly created reports).

The problem is simple: the expression class is no longer a required information in the model (it is not used at all by JasperReports anymore), so in old formats classes not defined become all java.lang.String, which may cause report errors.

In this case, iReport needs to be patched to eliminate invalid versions from the list of electable options.
