I'm trying to do a PATCH in Java, and I tried this solution PATCH request using Jersey Client
However, I'm getting this exception:
Exception in thread "AWT-EventQueue-0" java.lang.reflect.InaccessibleObjectException: Unable to make field private static final java.lang.String[] java.net.HttpURLConnection.methods accessible: module java.base does not "opens java.net" to unnamed module @6b29883d

This is the code that I added:
public static void modifyPATCH(final HttpURLConnection httpURLConnection, final String method) {
try {
Field methodsField = HttpURLConnection.class.getDeclaredField("methods");
methodsField.setAccessible(true);
// get the methods field modifiers
Field modifiersField = Field.class.getDeclaredField("modifiers");
// bypass the "private" modifier
modifiersField.setAccessible(true);
// remove the "final" modifier
modifiersField.setInt(methodsField, methodsField.getModifiers() & ~Modifier.FINAL);
// valid HTTP methods
String[] methods = {
"GET", "POST", "HEAD", "OPTIONS", "PUT", "DELETE", "TRACE", "PATCH"
};
// set the new methods - including patch
methodsField.set(null, methods);
} catch (SecurityException | IllegalArgumentException | IllegalAccessException | NoSuchFieldException e) {
e.printStackTrace();
}
}
And I'm calling it from this method:
public static void connectPATCHtoken(URL url, String token) {
try {
connection = (HttpsURLConnection) url.openConnection();
modifyPATCH(connection, "PATCH");
connection.setRequestMethod("PATCH");
connection.setRequestProperty("Content-Type", "application/json; utf-8");
connection.setRequestProperty("Accept", "application/json");
connection.setDoOutput(true);
String oauth = "OAuth " + token;
connection.setRequestProperty("Authorization", oauth);
connection.setConnectTimeout(5000);
connection.setReadTimeout(5000);
setConnection(connection);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
What am I doing wrong?
I updated the JDK to version 17 and it didn't help.
