you can try to increase heap space by adding e.g. "-Xms1024m" to the .bat-file. 
COr use command line "java -Xms1024m -jar xml2csv-conv.jar %*", if 1 GB RAM is 
enough for your file. I just try it with a > 200 MB XML-file and it seems to 
work, but takes quite a lot time. Smaller files did work!

I had the same issue with a file that was just over 500MB. Increased the memory 
of the JVM and left it to run over night. While the error wasn't produced, the 
process hadn't completed in over 12 hours. Killed the process in the end as the 
computer was very slow in responding.
