Research direction
Start at PluginLifecycleListener.java:109 and the surrounding initProxy call at line 65. Reproduce with IntelliJ IU-262.9437.185, plugin 3.97.7-2026.2, and JDK 25.0.3 on macOS, then trace why Authenticator.setDefault() becomes null instead of the customized provider. Done means the uncaught exception is resolved without breaking IDEA network calls.
