Description

Can’t get this to reproduce consistently, but sometimes when you restart an L1 app and reconnect with the same dev-console, it just locks up while loading the h2lc panel. There’s probably a classloading race in there. I found this in the logs, not sure it’s related but it might be a hint.

Verified with 3.1.0-nightly rev13396, dev-console launched with h2lcperf app, kill the L1’s, restarted L1’s and reconnected with the same dev-console multiple times working fine as expected
