This has been observed with large NITF, GIF and PNG files.

The attached test app demonstrates the behavior when run as:

java -d64 dfdl.test.api.dfdl.app.DfdlConverterApp -schema gif.dfdl.xsd -input GIF-TEST-IMAGE.gif -output out.xml -format xml

GIF-TEST-IMAGE.gif is too large to attach but can be provided
