Hi,

reading the exception, I see that the error is triggered here:

http://developer.classpath.org/doc/java/awt/image/ComponentSampleModel-source.html

which tries to create a DataBufferByte with negative (> 2G) size.  We
see that the JPEG200 RGB image is read into DataBufferByte instead of
DataBufferInt which results in a pixelStride of 3 or 4 depending on
whether there is alpha included.  This triggers the problem.

The method that is doing this, is

com.sun.media.imageioimpl.plugins.jpeg2000.J2KReadState.readAsRaster

used by

at com.sun.media.imageioimpl.plugins.jpeg2000.J2KImageReader.readRaster

used by

loci.formats.services.JAIIIOServiceImpl.readRaster

Assuming LOCI to be more responsive and attentive than Oracle I suggest
that you send them a mail telling them that their library uses a library
for JPEG2000 that does bad things.

Not using JPEG2000 for images of this size would probably solve your
problem for the time remaining.

Best,
Stephan
