Spring Download 1.1.8.RELEASE with spring-boot-starter-web dependency causes a hibernate-validator dependency, which in turn has a jboss-logging dependency.
The jboss-logging dependency causes jboss logging to capture log output from the log, which is also a dependency and is the usual logger for spring-boot. At least that's what happens to me. The logback.xml file is completely ignored even if you specify the logback.configurationFile system property at startup.
I know it is possible to exclude jboss-logging in maven or gradle, but is it really necessary? Should spring-boot-starter-web indicate the exception itself?
This is the result when the application starts:
12:56:42,137 [main] DEBUG org.jboss.logging - Logging Provider: org.jboss.logging.Slf4jLoggerProvider 12:56:42,145 [main] INFO ohvalidator.internal.util.Version - HV000001: Hibernate Validator 5.0.3.Final 12:56:42,206 [main] DEBUG ohvierDefaultTraversableResolver - Cannot find javax.persistence.Persistence on classpath. Assuming non JPA 2 environment. All properties will per default be traversable.
But if you remove the jboss-logging dependency with exclude in maven, at runtime you will get a stack trace from the application launch.
