Busy loop java.nio.file.ClosedFileSystemException; regression

[shoffmeister]

[provide a description of the issue]

Environment

• Operating System: Fedora 28 (current)
• JDK version: Oracle 10.0.2
• Visual Studio Code version: 1.27.2 (current -> repo)
• Java extension version: 0.32

Steps To Reproduce

1. start VS code
2. open (big) workspace containing a large set of mvn projects
3. open Java file
   // java file opens
   // vs code language extension welcome page opens
4. wait

-> builds automatically, but ends up with java.nio.file.ClosedFileSystemException in a busy loop (stack trace below repeats forever), shows "Failed to load tests" in the status bar.

Keeps the laptop hot and noisy.

Current Result

[Error - 18:46:01] 04.10.2018, 18:46:01 Problems occurred when invoking code from plug-in: "org.eclipse.core.resources".

Additional Informations

Searching Google for the exception message, I could not help but notice https://bugs.eclipse.org/bugs/show_bug.cgi?id=539536

[shoffmeister]

I would love to contribute a project, but my workspace is too large, sorry.

[fbricon]

Apparently JDT fixed their bug. Download the most recent java-<version>.vsix build and install it by following the instructions here.

Please report back here if that fixes your issue.

[shoffmeister]

I can confirm that java-0.33.0-1252.vsix makes the reported problem disappear.

[fbricon]

Cool. Thanks for checking.
