Spring-boot: Application is still running with "APPLICATION FAILED TO START" message

[izeye]

H2 is missing so the following "APPLICATION FAILED TO START" message has been printed but the application was still running:

$ ./gradlew clean bootRun

> Task :compileJava
Note: /Users/izeye/IdeaProjects/sample-micrometer-spring-boot/src/main/java/com/izeye/sample/web/SampleController.java uses unchecked or unsafe operations.

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
        If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
        If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

This is the sample project I used: https://github.com/izeye/sample-micrometer-spring-boot/tree/spring-boot-gh-16902

[jpmsilva]

Hi!
Just letting you know that I tested the sample provided and was able to reproduce it reliably.
The problem appears to be the same reported and fixed in #16892, because after the main thread dies, there are two non-daemon threads running, called Catalina-utility-1 and Catalina-utility-2.
After #16892 get's merged, this issue should be reviewed to check if it fixed.

Thanks for the sample, @izeye. As @jpmsilva suspected (thank you), this is the same problem as #16892 and it does not occur with the latest 2.1.6 snapshots where bootRun now fails:

./gradlew bootRun
