Language Support Fails to Start on MacOS: Error: Unable to generate a random pipe name with 7 characters.

bpeCRtMU commented 1 month ago

Upon closing and reopening VS Code the Java Language Server fails to start due to the following error:

[Error - 8:04:23 AM] Language Support for Java client: couldn't create connection to server.
Error: Unable to generate a random pipe name with 7 characters.
    at t.generateRandomPipeName (/Users/user/.vscode/extensions/redhat.java-1.30.0-darwin-arm64/dist/extension.js:2:1136512)

    at async c.start (/Users/user/.vscode/extensions/redhat.java-1.30.0-darwin-arm64/dist/extension.js:2:1156291)

Quitting and restarting VS Code does not solve this issue. However, restarting the computer and reopening VS Code works. Meaning the extension works again until you close the window.

Environment

Operating System: MacOS Sonoma 14.4.1 or Darwin arm64 23.4.0
JDK version: jdk-21, project jdk: 17
Visual Studio Code version: 1.89.1
Java extension version: 1.30.0

Steps To Reproduce

Open a Java Maven project in VS Code. The language server should start as normal.
Close the VS Code window (don't quit).
Reopen the Java Maven project in VS Code. The language server will fail to start.

Logs

The Java Extension did not produce a log file as it could not start.

VS Code:

Language Support for Java (Syntax Server) client: couldn't create connection to server.

Do you have XDG_RUNTIME_DIR defined ? Looks like it might be too long (>70 chars) on MacOS.

I'm getting the same error message.

How can we check for this var? I have not changed my environment in the last few days (although VS Code was updated).

Until this is fixed, try setting "java.transport" : "stdio" in your vscode settings. See https://github.com/redhat-developer/vscode-java/issues/3634#issuecomment-2096242414 for more details

Fred brought up a good point (in discussions), which is that we should be able to restart the language server with stdio if it fails the first time with pipe. The failure happens at https://github.com/redhat-developer/vscode-java/blob/2f5094fb858235120f55952cfb8f6ec987a1a4ac/src/TracingLanguageClient.ts#L32-L36, which is actually well before the initializationFailedHandler gets registered. This complicates relaunching.

Maybe we can improve this.
