POI invocation target exception

[thomas908 <an...@hcl.in>]

Is anyone aware of InvocationTargetException in POI (being used for reading
excel sheets).It is a very strange problem.
I have a swing based application which is reading excel sheets. Using this
application an excel sheet is selected and processed. After teh same excel
sheet is selected and processed a few times, it starts giving
InvocationTargetException. If I copy the content from excel sheet and put it
into another exel sheet and use that sheet, the problem disappears. It again
comes after that excel sheet is processed a few times.
The exception is thrown in the part of code which creates a workbook.

Here is the exception

java.lang.reflect.InvocationTargetException
