Error: The Language Support for Java server crashed 5 times in the last 3 minutes. The server will not be restarted.

This extension cannot start successfully and popup this error message. I found some logs in the output, hope it can help:
[Info - 11:24:22 AM] Connection to server got closed. Server will restart.

Environment

• Operating System: Windows 7 Enterprise
• JDK version: 1.8.0_40 (Setting JAVA_HOME environment variable only)
• Visual Studio Code version: 1.7.2
• Java extension version: 0.0.7

Steps To Reproduce

1. Download and install vscode 1.7.2
2. Search and install this extension: Language Support for Java(TM) by Red Hat
3. Open a .java file to start this extension
4. (Optional) Check the popup message and output logs

Additional Informations

I installed the same-version vscode and extension to another machine whose system is Windows 10, and the extension can work as expected.

Beginne damit, den Absturz mit den aufgeführten Schritten unter VS Code 1.7.2, Java extension 0.0.7, JDK 1.8.0_40 und Windows 7 zu reproduzieren, und untersuche dann die Ausgabe des language-server auf die wiederholten Verbindungsabbrüche und Warnungen zur Wiederherstellung des Arbeitsbereichs. Als erledigt gilt die Aufgabe, wenn die Java extension erfolgreich startet und nicht mehr den Abschaltzustand nach fünf Abstürzen erreicht.
