[OpenJDK 2D-Dev] [9] RFR JDK-8145014: "IIOException: Couldn't seek!" when calling TIFFImageReader.getNumImages()

[Brian Burkhalter]

Please review at your convenience.

Issue:  https://bugs.openjdk.java.net/browse/JDK-8145014
Patch:  http://cr.openjdk.java.net/~bpb/8145014/webrev.00/

In the locateImage() method handle zero-entry IFDs and EOFExceptions, hopefully 
returning the correct viable number of leading images in the stream with any 
bogus ones at the end being ignored.

Thanks,

Brian
