Research direction
Start by reproducing the uncaught exception with IntelliJ IU-242.23726.103, Windows 11, JDK 21.0.4, and plugin version 3.95.0-2024.2. Trace the reactive operation containing subscribeOnCallable and the 10-second timeout, then identify the triggering IntelliJ action and expected fallback or error handling. Done means the exception no longer appears for the reproducing case and a regression test covers it.
