What, exactly, is the problem you are having with Java + Xvfb ?

Back in my previous employer, we have headless servers on the data
center running Java applications. Some part of the applications
required loading / resizing / converting / adding watermark to image
files ... and for that, Xvfb was needed since the servers were
headless.
