What problem does this feature solve?
We used error tracking in all our projects. To be more precise, we use Flare for error tracking.

To better track an error we load the source maps to Flare accordingly. Now it is often the case that the stack trace is unreadable because the Vue source map seems to give only insufficient information. However, this does not always seem to be the case, sometimes the stack trace is easy to read.

Attached are a few screenshots that show the behavior well.

What does the proposed API look like?

You can use string to replace the int.

If the user has configured validateEdit to prompt before connecting, the connection to the server is done in UI thread.Connections are serialized using a Java synchronized block.This is can cause deadblock if another thread is connecting at the same time and is trying to prompt.
