Hi,

I'm trying to generate a PNG image of my process with ProcessDiagramGenerator.generateDiagram method, but this method throws an "javax.el.ELException: java.lang.OutOfMemoryError: Java heap space" exception. Possible reason for this exception is the size of my process, because I haven't encountered this problem while trying to generate an image for significantly smaller processes.

Have somebody resolved similar kind of issue?

Full stackstrace of an exception is as follows:

Generating an image uses Java2D, which generates the image completely in memory.
So yes,it could happen … but .. how much memory do you allow your app to have?
