Back to the old OS X conversion problem, I have noticed something interesting on the 7.0 release (have not tried it with other versions).
I ran JE-Comics on the first chapter of Death Note again. This Chapter contained 53 files. The first 10 being .jpg, the remaining 43 being PNG.
Taking the default settings on JE-Comics and hitting generate, it processed all 10 jpg with out and issue, but this time also managed to convert the next 9 .png files. Before erroring.
Code:

Now not being too up on my coding, would the fact that that JE-Comics was able to convert some of the png images, indicate that this is not necessarily a problem with the OS X version of Java.
This was tested with both J2se 1.4.2 and J2SE 5.0.
I have attached 4 pages from Death Note, on the off chance this can help in troubleshooting:
Death Note v01 c001 014.png
Death Note v01 c001 015.png
Which both converted fine, and then
Death Note v01 c001 016.png
Death Note v01 c001 017.png
Which failed the conversion.
All these files convert fine when on Windows
