"Invalid project description" thrown when opening Eclipse projects

I have used Eclipse Neon's Java project wizard to create a simple "Hello, World!" Java project (attached below). I then close Eclipse and open the project's root directory Test in VSCode. The first time I do this, everything works fine. But on all subsequent attempts to open Test in VSCode, the Java Language Server throws a ResourceException with the message "Invalid project description". The relevant lines of the Java Language Server's workspace log are included below. I believe I originally experienced this problem in April 2017, when I first started using this extension.

Environment

Operating System: Windows 10
JDK version: 1.8.0.131
Visual Studio Code version: 1.13.1
Java extension version: 0.6.0

Steps To Reproduce

Open the attached project's root directory in VSCode
Open src/pckg/Test.java from VSCode's file explorer
Wait for the Java Language Server to start up. It should load with no errors since this is the first invocation for this workspace.
Exit VSCode
Repeat steps 1 through 3. This time, the Java Language Server will fail to start, throwing a ResourceException with the message "Invalid project description".
