Description terje7601 2016-06-19 08:45:37 UTC
Build: NetBeans IDE Dev JDK9 Branch (Build 201606110404)
VM: Java HotSpot(TM) 64-Bit Server VM, 25.92-b14, Java(TM) SE Runtime Environment, 1.8.0_92-b14
OS: Windows 10

User Comments:
zmirc: Same as before. Here is the current code of the class (I know it doesn't compile, because it's not finished).

package dk.wordmaps.api.various;

import dk.wordmaps.api.boundary.util.exceptions.ApiCallException;
import dk.wordmaps.api.util.Config;
import dk.wordmaps.shared.util.JSONStringUtils;
import javax.servlet.http.HttpServletResponse;
import org.apache.http.StatusLine;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.json.JSONArray;
import org.testng.annotations.Test;

public class Danskkulturarv {
    private static final CloseableHttpClient HC = HttpClients.createDefault();
    public void step1() {
	HttpGet get = new HttpGet("");
	try (CloseableHttpResponse r = HC.execute(get)) {
	    StatusLine sl = r.getStatusLine();

GUEST: I was doing a copy paste of a entire method(signature and contents) from source file A into source file B. The paste location was located in a method of source file B. The resulting code had a method in a method then the error instantly occured.

jan.kurnatowski: while editing Java code

GUEST: Adding a try with resrouces statement with a Callable Statement

GUEST: I was just typing code.

GUEST: Error when declaring "try with resources"

chunkyks: Create a new file, I called mine "NewClass"

Enter this code:
public class NewClass {
    public int test(Connection c) {
        PreparedStatement s = c.prepareStatement("SELECT 1");
        return 0;

Obviously this is broken

So manually edit the code to change it to a try-with-resources, and this crash happens. Before "PreparedStatement", manually enter "try(", then delete the semicolon from the end and put in close parentheses. Instant crash

seligor: NullPointerException during source editing

tboudreau: Typing in editor

atehrani: Copy/paste

jan.kurnatowski: while editing Java code...

vriha: pasted code from one class to another and used code completion

jan.kurnatowski: while editing Java code (I have restarted IDE after reporting Exceptions 788010 788009 788007 and tried to reproduce this issue)

GUEST: did an if statement
opened the brace { and hit return

GUEST: <Please provide a description of the problem or the steps to reproduce>

vriha: copy pasted java code from one method to another

terje7601: Same ...

terje7601: Coding Java

terje7601: Working on Java 9 code

zmirc: Same as before. It's probably because I've just deleted the "catch" part of a try catch while I was doing some refactoring.

GUEST: Error when declaring "try with resources"

tboudreau: Pasting

zmirc: Working with try catch in a Java method inside a TestNG test class

fordfrog: This error occurred after writing

try (final RS

and pressing Ctrl+Space. AFAIK exceptions are fired until i close the ( with corresponding ) plus {} block and start the catch statement. The bug is there for more than week a guess, probably even longer.

jskrivanek: I pasted block of code to a method.

sreder: Just typing java code

Lolmewn: Copy pasted a piece of code which included a try-with-resources block without a throw/catch block yet (was gonna add that with the help of hints but got this error instead). Also returns a boolean while method type is void.

lvaills: I just removed a catch block from try with resources.

gtzabari: Saved file. Exception thrown.

GUEST: happened after closing merge screen

GUEST: just editing


jan.kurnatowski: while editing Java code

jskrivanek: I removed catch block and method became uncompilable.
