It looks like something about your images/system is causing ImageIO.write to fail. My best guess is that it's returning that there are no available ImageWriters, but the compiler incorrectly does not read the return value.
Any time the compiler dies with an NPE, we consider that a compiler bug. I should have a patch later today to fail on this condition a bit more gracefully. That said, the root cause will still mean your build won't complete.
