vscode-java-debug Error: It is not possible to provide debug adapter executable.

Bug Description:

root ERROR Error starting the debug session Error: It is not possible to provide debug adapter executable.
    at DebugExtImpl.<anonymous> (/home/NETZAGENTUR/josef/git/theia/packages/plugin-ext/lib/plugin/node/debug/debug.js:709:39)
    at step (/home/NETZAGENTUR/josef/git/theia/packages/plugin-ext/lib/plugin/node/debug/debug.js:33:23)

    at processTicksAndRejections (internal/process/task_queues.js:94:5)

Steps to Reproduce:

1. git clean -fxd; yarn; yarn run start:electron or yarn run start:browser
2. manually install redhat-java@0.74 and vscode-java-debug@0.30 extensions
3. configure debugging configuration
   { "version": "0.2.0", "configurations": [
   { "type": "java", "name": "Debug localhost", "request": "attach", "hostName": "localhost", "port": 9999}]}

when opening a java source file, theia starts a java process, code completion aka intellisense also works perfectly.
so, redhat-java extension seems to work.
but vscode-java-debug seems not to start up correctly.

• Operating System: Ubuntu 20.04
• Theia Version: master branch, v1.0.10, v1.0.9

@joho1001 - opened PR #9035 for this issue. I'm not sure it solves all issues and renders java debugging fully operational on Theia but managed to run basic debug on java project - also not sure that Theia is the most comfortable IDE for it but for starters let's see if it works for you.
Thanks
