Re: [Geotools-gt2-users] Win 64bit problems: alternatives to reading tiffs with ImageIO?

[Ferdinando V. <fv...@uv...>]

Thanks Jody. The issue is not as much running on Win64 but running there 
on a 64bit JVM. Is this what you're referring to with the uDig success 
story? We've been running so far on Win64 but using a 32bit JVM, 
unfortunately we now need the larger address space.

Unfortunately others have asked and got no luck - apparently Sun has 
essentially abandoned the project(s) a while ago, and the source is 
released only for the non-native parts of the libs. Needless to say, 
ImageIO does not have a pure Java option like JAI does.

Thank you, ferdinando
