When run as a service on a windows machine (using the simple wrapper method), I get an IOException - Insufficient system resources exist to complete the requested service for large files. Large seems to be anything above 66 Mb and always causes the same error message. I adjusted the jvm min/max to 64 and 512 (and 1024), with still the same result. The exception is thrown when reading the file into the byte array.
