Now, this is one of the things that should never happen. This is a JVM
crash, so you're hitting a JVM bug (at most the JVM should state it cannot
allocate memory, never crash like this).

Well, if you are in the business of handling large raster requests 1GB
might not be enough, pump up -Xmx to something higher (do the math, how many
concurrent requests do you want to handle? How much memory do they consume?)
And then probably you want to lower the JAI settings back to their original
values?
