dev mode doesn't recover when an invalid value (typo, space) is added to logging level configuration

[rsvoboda]

Dev mode doesn't recover when an invalid value (typo, space) is added to logging level configuration
When the value is corrected, Quarkus still isn't able to restart itself.

Reproducer:

mvn io.quarkus:quarkus-maven-plugin:1.3.2.Final:create \
    -DprojectGroupId=org.acme \
    -DprojectArtifactId=getting-started \
    -DclassName="org.acme.getting.started.GreetingResource" \
    -Dpath="/hello"
cd getting-started
mvn quarkus:dev

open src/main/resources/application.properties
add 'quarkus.log.category."org.hibernate".level=DEBUG ' (extra space at the end) into application.properties
open http://localhost:8080/hello
remove extra space at the end of quarkus.log.category line in application.properties
open http://localhost:8080/hello

Log reports:
