From http://java.net/jira/browse/MACOSX_PORT-786 --

Many times running 2D functional tests automated or manual there are failures because some files cannot be created. Each time the error message is something like:

java.io.FileNotFoundException: /2d/test/2d/data/2D_ImageIOTiger/images/duke.gif (Too many open files)

ulimit -a for the system showed:
open files (-n) 256

I can change this to a greater number but that would just be workaround to larger problem that is just starting to occur.

Test Affected (other will be added as they show up):
2D_ImageIOTiger/ImageIOReaderDestTest
2D_ImageIO/AutoImgEncodeDecodeLLTest
2D_ImageIO/AutoSequenceFISBISFCIISTest
