I think it should be possible with standard remote debug:
1) create a 'Remote' IDEA run configuration 2) launch appclient and pass debug VM options to it via the command line 3) start the created 'Remote' IDEA run configuration
The workflow is actual if you choose 'Attach' debugger mode in the 'Remote' IDEA run configuration. If you choose 'Listen', then step 3) should be done before step 2).
