I am using Sun's Java Advanced Imaging (JAI) and Java Advanced Imaging-
Image I/O (JAI-IMAGEIO) on the server side of my application for
reading and processing TIFF's and other images which are then scaled,
converted to PNG, and sent to the browser.
Today I downloaded and installed GWT 2.0.0. In attempting to run the
sample Showcase, I receive javax.imageio.IIOException's on the JPG
images, like jimmy.jpg. This happens only if the $JAVA_HOME I'm using
has JAI and JAI-IMAGEIO installed. Without JAI, the JPGs open fine.
(Note: Yesterday with GWT 2.0.0 RC2 I was able to modify the JPGs by
converting them to/from PNG but that trick is not working today).
The stack trace strikes me as screwy, since the images start with the
proper 0xff 0xd8 0xff 0xe0:
00:00:22.020 [ERROR] Unable to read image resource
javax.imageio.IIOException: Not a JPEG file: starts with 0xff 0xd9
