- Plugin written in Java, not Kotlin - Current 2025.3 EAP I’m using `PasswordSafe` in a configurable to store settings, but with 2025.3 there’s an exception now. `reset()` of the configurable is invoked in a `ReadAction` and access `PasswordSafe`. But the `PasswordSafe` is only used in a `Task.WithResult` to read the password in a background thread. With 2025.3 (tested with the current EAP), I get an exception. This seems to happen because the `ReadAction` is inherited now by the code executed inside `Task.WithResult`. How can I fix this if it’s not possible anymore to move things outside the ReadAction? I need to return the password retrieved from the password safe. Code: ```auto if (ApplicationManager.getApplication().isDispatchThread()) { var title = "..."; cachedSettings = ProgressManager.getInstance().run(new Task.WithResult(null, title, false) { @Override protected CachedSettings compute(@NotNull ProgressIndicator indicator) { // this is invoking PasswordSafe.getInstance().getPassword(...) return loadSettingsInBackground(); } }); } ``` Stacktrace up to the ReadAction setup: ```auto java.lang.Throwable: Non-cancelable slow operations are prohibited inside read action.
