Extension Doesn't work if Flight Recorder is Enabled

With JFR enabled, the extension does not work at all.

Environment

• Operating System: Mac OS
• JDK version: OpenJDK 14
• Visual Studio Code version: 1.44.2
• Java extension version: 0.60.0

Steps To Reproduce

1. Enable JFR in User settings with the following setting:

"java.jdt.ls.vmargs": "-XX:StartFlightRecording=settings=default,dumponexit=true,filename=/Users/bruno/jfrdumps -Xms512m",

2. Restart extension

3. Try to work on any Java project

Current Result

Nothing works.

Expected Result

Should work same way as without JFR.

Additional Informations

The language server JVM is up and running and things are happening inside of it. When you quit VS Code or terminate the JVM, a JFR dump will be produced and will highlight thousands of Errors/Exceptions.

まず、java.jdt.ls.vmargs 設定と JFR を有効にした状態で失敗を再現し、その後、JFR の有無による language server の JVM の動作を比較します。Java プロジェクトの操作が機能しなくなる理由を追跡し、要求された JFR dump を引き続き生成しながら、拡張機能が正常に動作することを確認します。
