Have you tried with the latest version of POI? There have been some fixes
of late for this sort of thing
The problem occurs even when the excel sheets are empty and I've traced
the cause as being resized columns above the WWH1 range.
According to visualVM, the following methods are where most of the time is
spent:
org.apache.xmlbeans.impl.store.Locale.count() 48.6%
org.apache.xmlbeans.impl.store.Xobj.find_element_user()
47.9%
What in POI was calling xmlbeans? And what kinds of objects was xmlbeans
searching for?
