FULL PRODUCT VERSION :
java version "1.8.0_71"
Java(TM) SE Runtime Environment (build 1.8.0_71-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.71-b15, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Windows 7 64 bit

A DESCRIPTION OF THE PROBLEM :
I am ensuring stability for a image manipulator program. This bug occurs with javax.imageio.ImageIO.read(File file) when reading in corrupted JPG or PNG images. Depending on how I corrupt the file this function can throw java.lang.NullPointerException or a java.lang.ArrayIndexOutOfBoundsException in addition to the IOException that the documentation stated.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I corrupted the files by opening them in notepad and adding and/or deleted tandom peices of the data. The java.lang.ArrayIndexOutOfBoundsException occured more often with the JPG with data altered in the middle of the file, while java.lang.NullPointerException occurred with edits in both middle of png file and jpg's header. Then I just tried to load them with ImageIO.read(new Fille("fileName"));

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I was expecting only an IOException.
ACTUAL -
 java.lang.NullPointerException or a java.lang.ArrayIndexOutOfBoundsException
