Description

1. Start profiling session of Maven project in "Objects" mode. This works fine.
2. Switch mode to "Telemetry". This works fine.
3. Switch mode back to "Objects".
4. Output window reads:

   Profiler Profiler Agent Error: Exception when handling command from client:
   java.io.IOException: JFluid wire protocol error: code does not correspond to command or response. Value -1

5. UI remains empty (no values show up). Program keeps on running but profiler no longer displays any values even if mode is changed again.
6. The only thing a user can do at this point is kill the profiling session and restart
