java.lang.ArrayIndexOutOfBoundsException: 5
	at jxl.biff.IndexMapping.getNewIndex(IndexMapping.java:68)
	at jxl.biff.FormattingRecords.rationalize(FormattingRecords.java:388)
	at jxl.write.biff.WritableWorkbookImpl.rationalize(WritableWorkbookImpl.java:988)
	at jxl.write.biff.WritableWorkbookImpl.write(WritableWorkbookImpl.java:692)
	...


It appears that this exception occurs only when you try to generate more than one Excel spreadsheet! How strange is that! 8-O
After a bit of investigation, it seems that the problem comes from the use of the static modifier with a jxl.write.WritableFont variable.

I unfortunately don’t have the time to check the JExcelAPI code source to understand the root cause.
So my advice would be: “if you get EXACTLY the same stack trace, simply delete any static modifier you used with the WritableFont variables”. :-)
