Product: POI
Version: 3.8-dev
Platform: All
OS/Version: All
Status: NEW
Severity: critical

Java code and Excel files to reproduce the getDataFormatString crash
The getDataFormatString method call crashes when reading the test file
test-data\spreadsheet\12561-1.xls
with the following stack trace.
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Array
index out of range: 56
at java.util.Vector.get(Vector.java:694)

at org.apache.poi.ss.examples.ReadDataFormat.main(ReadDataFormat.java:34)
This happens in both poi-3.8-beta3 and poi-3.7.
I tested another Excel file and found that it failed with similar stack trace
in poi-3.8-beta3 but succeeded in poi-3.7. I believe there is a regression
here.
Please see attached source code and two Excel files to reproduce this issue.
