cant remote debug on tomcat via attach

i'm trying to remote debug my application, which is running on a tomcat.

Environment

• Operating System: mac OS 10.14.4
• JDK version: 1.8.0_131
• Visual Studio Code version: 1.34.0
• Java extension version: 0.7.1
• Java Debugger extension version: 0.18.0

Steps To Reproduce

my configuration:

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [
    {
        "type": "java",
        "name": "Debug (Attach) - Remote",
        "request": "attach",
        "hostName": "localhost",
        "port": 8090
    },
  ]
}

[attach a sample project reproducing the error]
attach logs

Current Result

i'm getting an error message in vscode: Timeout occured while waiting for packet 106

Expected Result

debugger attaches to the remote tomcat just fine

Additional Informations

the same configuration works with intelliJ idea, so it should work in vscode.
idea connects fine with host: localhost, port: 8090
idea shows these params: -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8090
do i have to add them somewhere for vscode?

先查看提供的啟動設定和疑難排解記錄說明，然後將 VS Code 的附加路徑與 IntelliJ 使用的 JDWP 參數進行比較。完成標準是找出 localhost:8090 上的 Tomcat 目標逾時的原因，並確認偵錯工具成功附加。
