Problem Statement/Rationale

Currently when you open a new Java file, you have to reselect the datastore even when you're in the same IntelliJ session. This is not ideal UX as it requires users to take an action each time a Java file is opened. 

Please be sure to attach relevant logs with any sensitive data redacted.
How to retrieve logs for: Compass; Shell

Steps to Reproduce{}

1. Open a Java file (e.g. File1.java) & select a MongoDB datastore in the tool bar
2. Open a new Java file that also has MongoDB code in it (e.g. File2.java)
3. Notice the toolbar in the File2.java doesn't have a datastore selected 

{}Expected Results

In Step 3 above, the toolbar in File2.java should also the same datastore selected as File1.java.
