EXTRA RELEVANT SYSTEM CONFIGURATION :
Nothing relevant.
A DESCRIPTION OF THE PROBLEM :
The TIFF codec throws an IllegalArgumentException when determining the number of pages in some TIFFs (the TIFFs in question appear to be corrupt). Even though the files in question are corrupt the TIFF codec should not be throwing a RuntimeException! At the very least, if you guys feel it is valid for the codec to be throwing a RuntimeException when a file is corrupt it should be documented. I've tested this behavior with the codec bundled with JAI v1.1.1 & v1.1.2, both exhibit the same bug.
I can provide several corrupt tiff files that cause this behavior.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the test case below on a corrupt tiff file...
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
In the case of a corrupt tiff I was expecting either an IOException to be thrown or simply -1 to be returned. The javadoc isn't clear what the behavior will be in the case of a corrupted file.
ACTUAL -
An IllegalArgumentException (RuntimeException) resulting in an application crash.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
Exception in thread "main" java.lang.IllegalArgumentException: Bad endianness tag (not 0x4949 or 0x4d4d).
at com.sun.media.jai.codec.TIFFDirectory.getNumDirectories(TIFFDirectory.java:588)
at com.sun.media.jai.codecimpl.TIFFImageDecoder.getNumPages(TIFFImageDecoder.java:105)
at com.kelman.testcase.TiffCodecBug.main(TiffCodecBug.java:42)
REPRODUCIBILITY :
This bug can be reproduced always.
