hkuadithya
commented
4 years ago @fbricon It's just a simple standalone Java file with a main method. Not using Gradle/Maven.

4 years ago did you simply open the java file or its parent folder?

commented
4 years ago File > Open Folder (empty folder)
Created a new Java file from the Explorer in the left panel. New File > Functional.java.
Debug > Run Without debugging -- Works fine. However, when I add var, errors are raised.
Examples for errors:
var array = new int[]{1, 2, 3, 4};
var hello = "hello world";This works fine:
int[] array = new int[]{1, 2 ,3, 4};
String hello = "hello world";Please turn on verbose logging and attach the logs from the output view, after restarting vscode

4 years ago It works for me on Mac. @snjeza can you double check on windows?
hkuadithya
commented
4 years ago @fbricon Sure, I'm currently at work. Will provide more details (verbose logging) when I get back home in about 6-7 hours (PST timezone).
Since it works on Mac, I suspect it's specific to the OS. (Win 10 Professional, 64 bit).

I can't reproduce the issue on Windows and Linux. @hkuadithya Could you attach your Functional.java?

There were lots of traces. I picked the one displayed first. Trace with verbose logging. I parsed it in a JSON parser to make it readable.

4 years ago @hkuadithya You can also try to call Java: Clean the Java language server workspace

4 years ago @fbricon @snjeza Yes, "Java: Clean the Java language server workspace" worked. I suppose it's some language server caching issue. I also recently updated my JDK from JDK9 to JDK13. Not sure if that caused this problem.
Let me know if you guys need anything else for the RCA of this issue. Please feel free to close this issue. Just keeping it open on my end if you guys decide to RCA this.

4 years ago @snjeza the default JDK should have been updated to JDK 13, so something's still not right here. Please investigate.

4 years ago To make sure I'm not jumping the guns, @hkuadithya how did you change the JDK version exactly? via java.home?

4 years ago @fbricon Maybe this will help you reproduce the issue:-
Before updating JDK: I created a new folder and added new file Functional.java
I was able to build and run without any issues. Since it was JDK9, my code didn't have any vardata type
I uninstalled old Java, updated my JDK to 13, updated the path in environment variables and restarted the system
Opened VSCode, and added var to code to test type inference. Build and compilation failed. javac worked though
I thought that vscode wasn't picking the right Java version or maybe JDK13 wasn't supported yet since it was released recently.
I checked "Configure Java runtime"and saw that JDK13 path was already present under option 4 (source: other).
I added the same path for option 1 under user settings json hoping that it would force the language server to pick the features from latest JDK. Restarted vscode and tested. That didn't work either.
TLDR; vscode had automatically detected the jdk path under "other". I also added the path to option 1 "Java.home" hoping that language server would refresh. That's why I think it's an issue with the language server caching. Although, ideally the cache must be invalidated when the Java version is changed.

4 years ago @fbricon @snjeza Looks like this is an isolated case/issue which occurs under some weird set of circumstances. I couldn't find any other issues resembling this under Open Issues. You folks could focus more time and resources on this if similar issues are opened in future.
I will close this issue for now. Thank you for investigating this. Please reopen if this warrants further investigation.
Issue Type: Bug
VSCode Java extension seems to raise error while using
vardata type (type inference for local variables was introduced way back with Java 10). Running the project also seems to fail while usingvardatatype.There's absolutely no problem with my Java environment. Compiling and running the same Java file using
javacandjavasucceeds in command line. This works fine with IntelliJ IDEA as well. Please check the screenshots of the error and Configure java runtime.Is there some setting or configuration I need to change?
Java environment details:
Error
Configure java runtime - JDK 13
Extension version: 0.8.1 VS Code version: Code 1.42.1 (c47d83b293181d9be64f27ff093689e8e7aed054, 2020-02-11T14:45:59.656Z) OS version: Windows_NT x64 10.0.18362
