This is not an iText problem. Have a look at:

> at sun.nio.ch.FileChannelImpl.map(FileChannelImpl.java:731)
try {
// If no exception was thrown from map0, the address is valid
addr = map0(imode, mapPosition, mapSize);
} catch (OutOfMemoryError x) {
// An OutOfMemoryError may indicate that we've exhausted memory
// so force gc and re-attempt map
System.gc();
try {
Thread.sleep(100);
} catch (InterruptedException y) {
Thread.currentThread().interrupt();
}
try {
addr = map0(imode, mapPosition, mapSize);
} catch (OutOfMemoryError y) {
// After a second OOME, fail
throw new IOException("Map failed", y);
}
}

No, but reading the code, I'd say it's an OutOfMemoryError.
