Pending operations left around after executing JS files #455
Description
I'm using latest Eclipse 4.16 with latest Wild Web Developer 0.10.0.202006021616. Launching a Node.js application within it always leaves behind pending operations in the background.
-
Using the Run As -> Node program context menu to launch the execution of a JS file finishes in the Console view, but leaves a progress bar saying "Launching <path_to_file>.js", hung at 37%, in the Progress view. No errors show up in the workspace log.
-
Using a launch configuration named "lang" of type Node.js application for the JS file in question exhibits the same problem. But the workspace log contains this:
!ENTRY org.eclipse.ui 2 2 2020-06-24 21:19:44.131
!MESSAGE Invalid property category path: org.eclipse.cdt.managedbuilder.ui.properties.Page_head_build (bundle: org.eclipse.cdt.ui, propertyPage: org.eclipse.cdt.managedbuilder.ui.properties.BuildLogPreferencePage)
!ENTRY org.eclipse.core.jobs 4 2 2020-06-24 21:19:44.348
!MESSAGE An internal error occurred during: "Launching lang".

Occasionally, the execution itself hangs, i.e the Console view is frozen, too. I tried a few cases, but cannot indicate a reproduction scenario for this, as well.

I think it's related to this bug/patch targetting LSP4E by @vrubezhny : https://git.eclipse.org/r/c/lsp4e/lsp4e/+/164428 , so hopefully, when this is merged and LSP4E releases the fix, things will work properly,

I doubt that.
The patch description speaks about failed launches and that is not the case here - the launches succeed.
