@guw could the log entry below, which I've just seen for the first time (perhaps newly visible since I add -Djava.bazel.staticProcessStreamSocket=22222 here after #97 from @lonhutt and/or after your f593594 for #100?) possibly be that long elusive root cause why for me on a new workstation it "doesn't work"?

The "end-user visible effect" here is like I previously described: The extension's Runtime Status is activated, "Activation Event:onLanguage:java, Activation Time: 13ms", but the Java Projects view/tab is just "spinning" - it failed to start / initialise.

PS: Maybe this is even related to #94 ?

The log is too long to copy/paste, here's just the end, I'm attaching the full .log:

Actually, after a Clean Java Language Server Workspace this went away... so I cannot actually reliably reproduce these errors. (I'm seeing different issues now; and will open separate bugs for those.)

Not sure if this a concurrency bug or just "cosmic rays" or if there is something that the extension could do (some initial clean up?) to prevent this?

Your call if you want to keep this open or close this.

Closing as #obsolete (it works great for me right now).

@vorburger vorburger closed this as not planned Won't fix, can't repro, duplicate, stale Apr 14, 2024
