Cannot invoke o.e.j.i.c.u.JrtFileSystem.walkModuleImage() #1212

TBug001 · 2022-09-04T08:06:52Z

Type: Bug

I'm not much of a GitHub user, so let me briefly describe my problem.

I don't know since when I use VScode to open Java files, I will be prompted to use JDK17, but at this time, I can still use DEBUG. After a period of time, when I use it again, the DEBUG will not be able to use, and the following error will be displayed. I guess it is the problem of the plug-in "Debugger for Java", but I can't solve it after lowering the version.

Cannot invoke "org.eclipse.jdt.internal.compiler.util.JrtFileSystem.walkModuleImage(org.eclipse.jdt.internal.compiler.util.JRTUtil$JrtFileVisitor, int)" because the return value of "org.eclipse.jdt.internal.compiler.util.JRTUtil.getJrtSystem(java.io.File, String)" is null

Having the same issue but on Linux with openjdk 17.

amwestrich · 2022-09-05T19:32:00Z

The version from two months ago, v1.8.2022062904 doesn't have the issue.

testforstephen · 2022-09-06T01:56:35Z

@TBug001 @amwestrich Could you please provide more details (e.g. the full exception log) about this error? It's better to provide a sample project for us to reproduce the error.

bib1963 · 2022-09-08T10:18:31Z

I see this as well. It needs nothing special, just create a new java project and the error will appear. The only source file is the default App.java which is automatically created.This is with Linux with java-11-openjdk-devel-11.0.16.0.

I see exactly the same issue in the new 2022-09 release of eclipse using openSUSE Leap and OpenJDK Runtime Environment 17.0.4+8 as soon as one of my Java projects start building.

jadavis42 · 2022-09-15T14:17:27Z

@amwestrich is correct. I downgraded Language Support for Java(TM) by Red Hat to older version v1.8.2022062904 and the problem goes away. I'm using VS Code on Windows 10 with jdk 17

The NPE above is the reason for the failure, it occurred when Java extension tried to parse your JDK info such as jrt-fs.jar, release. This issue seems related with the JDK installation.

Could you provide more information about the JDK installation you use?

What JDK distribution do you use? How do you install it?
If you're using Linux or macOS, check if your JDK related settings (e.g. java.home, java.jdt.ls.java.home, java.configuration.runtimes) point to any JDK location with symlink.

@testforstephen Windows10 JDK13

testforstephen · 2022-09-16T05:39:18Z

Usually, this folder should include a release file, which contains the JDK vendor info.

@TBug001 Could you check if release file is missing in your JDK installation?

testforstephen · 2022-09-16T06:02:34Z

I think I eventually reproduced the issue. If I manually delete the release file from my JDK installation, then Java extension will throw the NPE error above. Adding it back, then it works again. Java extension does not handle the missing release file well.

As far as I know, most of JDK vendors will include a release file. So I'm wondering what JDK distribution do you use? How do you install it? By Intellij IDEA, http download, package manager?

TBug001 · 2022-09-16T06:36:32Z

The problem was solved according to your method. I re-downloaded a 13.0.2 JDK and copied its release file. Now it works properly. I don't know why the release file is missing, but I think I installed it three years ago via HTTP download

TBug001 · 2022-09-16T06:43:13Z

The reason for the problem is the lack of release file. Thank you very much for testforstephen's kind answer!

maresmar · 2022-09-19T12:07:34Z

Here are steps how to get release file for yourself 😄

We want to know if it is rare for JDK builds to not contain "release" files. So can you tell us the affected JDK distribution and version? Where can we get it from?

TBug001 · 2022-09-19T12:43:23Z

@testforstephen Now there is a new problem that will show up when I press "F5" to debug, I have to manually click the "Proceed" button to debug

testforstephen · 2022-09-19T12:56:05Z

@TBug001 You can set the setting java.debug.settings.onBuildFailureProceed to always proceed.

TBug001 · 2022-09-19T12:58:36Z

@TBug001 You can set the setting java.debug.settings.onBuildFailureProceed to always proceed.

ok

maresmar · 2022-09-20T08:39:19Z

So can you tell us the affected JDK distribution and version? Where can we get it from?

I use Java 11 from OpenSUSE Tumbleweed in WSL 2.0

$ cat /etc/os-release

# VERSION="20220917"
...
$ sudo zypper info java-11-openjdk-devel

testforstephen · 2022-09-20T13:08:58Z

@maresmar thanks for sharing your use case. Good to know that JDK in OpenSUSE doesn't contain release by default.

In the meantime Java 11 and Java 17 have been updated for openSUSE Tumbleweed and should work nicely:

> rpm -q java-17-openjdk-headless
java-17-openjdk-headless-17.0.4.0-2.1.x86_64

> rpm -ql java-17-openjdk-headless | grep release
/usr/lib64/jvm/java-17-openjdk-17/release

H-Lo · 2023-03-08T01:45:52Z

I can confirm that missing release file causes exception. But not only that: maven update cannot be done and Eclipse tries again and again in a loop and my pretty fast computer becomes unusable. It takes one minute to open Windows task manager and brutally kill Eclipse.
One relatively not important file missing shouldn't be the reason to destory the whole OS with indefinite loops for sure.
