java crash_Java Crash while downloading File
I want do download a big .jar file from my own Server. (https://luis.team) There for I made a thread to download it, because it is very huge. Here is my code for download:
public Update(String version, File outputFile) {
URL url;
URLConnection connection = null;
try {
url = new URL(“https://raw.githubusercontent.com/Luuuuuis/InstantVerify/master/version“);
connection = url.openConnection();
} catch (IOException e1) {
e1.printStackTrace();
}
assert connection != null;
try (BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()))) {
String[] versionCode = in.readLine().split(“&&”);
if (!(versionCode[0].equalsIgnoreCase(version))) {
/*
* Download from URL given in version file
*/
if(versionCode[1] != null && !versionCode[1].equalsIgnoreCase(“null”)) {
Thread th = new Thread(() -> {
try {
URL downloadURL = new URL(versionCode[1]);
URLConnection urlConnection = downloadURL.openConnection();
urlConnection.setRequestProperty(“User-Agent”, “Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36”);
InputStream inputStream = urlConnection.getInputStream();
OutputStream outputStream = new FileOutputStream(outputFile);
byte[] buffer = new byte[1024];
int length;
while ((length = inputStream.read(buffer)) != -1) {
outputStream.write(buffer, 0, length);
}
inputStream.close();
outputStream.close();
InstantVerify.version += “ (outdated)”;
} catch (Exception ex) {
ex.printStackTrace();
}
});
th.start();
}
} else {
InstantVerify.version += “ (latest)”;
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
After this I get a very little file(around 30MB) and an Java Runtime Error:

I guess there is a issue with Memory Mapping in Java, because my root Server has only 2GB of RAM. What can I do do fix this? Thank you.
