HotTests option causes 30 second timeout after build.gradle change

[turkeylurkey]

Use LGP 3.3 and a project like demo-devmode. Start dev mode with:
gradle clean libertyDev --hotTests

After the server starts, edit the build.gradle and change the dependency providedCompile 'org.eclipse.microprofile:microprofile:4.1' to 3.3. Save the file.

Tests finished.
Tests will run automatically when changes are detected. You can also press the Enter key to run tests on demand.

Running tests...

After the server starts dev mode runs the tests. After build.gradle is changed dev mode does not rebuild but it does attempt to run the tests. Dev mode times out waiting for an app update.

Should dev mode rebuild after a dependency is changed?
Should dev mode run the tests if no build was initiated?
