Deadlock during validateEdit call in UI thread #814

Closed ysong10 closed 4 years ago

ysong10 commented 4 years ago

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

@ysong10 Can you provide this information in the bug report?
