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.

まず、VS Code 1.7.2、Java extension 0.0.7、JDK 1.8.0_40、Windows 7 を使用して、記載されている手順でクラッシュを再現します。次に、language-server の出力を調べ、接続が繰り返し切断されていることと、ワークスペースの復旧に関する警告を確認します。Java extension が正常に起動し、5 回のクラッシュ後のシャットダウン状態に到達しなくなれば完了です。
