The issue is related to the zig-zaged coloured background. When we calculate the tile size we get some really large image values which is causing the memory issue. I'll need to do some work here to figure out what is going wrong with this PDF.

The zig-zaged background has incorrectly recorded step value for the tiling definition As a result we try to paint a very large image tile and pop the jvm. We have a text for such a case but due to a small logic error this corner case was not caught. Update the step dimension check and PDF now renders correctly.

Marking as fixed.
