Subject:    java.io.IOException: Dbf has extra record" when opening
       Shapefile


When opening ESRI shapefiles with the ShapefileDataStore (see code belo=
w),
some shapefiles produce an java.io.IOException ("Dbf has extra record")=
.
The affected shapefiles itself are ok. They can be opened by ArcInfo,
ArcExplorer or e.g. shapelib without problems. Sample shapefile: (See
attached file: testShapefile.zip)

The stacktrace is:
java.io.IOException: Dbf has extra record
at
org.geotools.data.shapefile.ShapefileDataStore$Reader.hasNext(Shapefile=
DataStore.java:417)

at org.geotools.data.FIDFeatureReader.hasNext(FIDFeatureReader.java:133=
)
at
org.geotools.data.DefaultFeatureResults.collection(DefaultFeatureResult=
s.java:227)
