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.

Inizia riproducendo il crash seguendo i passaggi indicati con VS Code 1.7.2, Java extension 0.0.7, JDK 1.8.0_40 e Windows 7, quindi esamina l’output del language-server alla ricerca delle chiusure ripetute della connessione e degli avvisi sul ripristino dell’area di lavoro. Il lavoro è completato quando Java extension si avvia correttamente e non raggiunge più lo stato di arresto dopo cinque crash.
