---------------------------------------

I'm able to reproduce this issue with Tika 1.8-SNAPSHOT. Didn't investigate beyond that.

> I have an example ppt that embeds a chart, but Tika mis-identifies it
> as an XLS document.
> The progID (oleShape.getProgID() in
> HSLFExtractor.handleSlideEmbeddedResources) is MSGraph.Chart.8 ... and
> we seem to detect it as Excel (application/vnd.ms-excel) but then the
> ExcelExtractor hits this exception:
> {noformat}
> org.apache.poi.hssf.record.RecordFormatException: Unable to construct record instance
> 	at org.apache.poi.hssf.record.RecordFactory$ReflectionConstructorRecordCreator.create(RecordFactory.java:65)
> 	at org.apache.poi.hssf.record.RecordFactory.createSingleRecord(RecordFactory.java:301)
> 	at org.apache.poi.hssf.record.RecordFactoryInputStream.readNextRecord(RecordFactoryInputStream.java:285)

> 	at org.apache.tika.parser.microsoft.ExcelExtractor.parse(ExcelExtractor.java:147)
> {noformat}
> Since DelegatingParser silently suppresses all exceptions, when you
> run TikaCLI you won't see any exception nor text extracted, but if you
> run with -z, it will save 1.xls which if you then try to parse with
> TikaCLI hits the above exception.
