I am using 1.3.0 logback-classic version, my application stops logging. The logback.xml file maybe isn't even loaded (if I insert invalid xml or delete it, I get no errors).

It works fine with logback 1.2.6.

This works:

logback-classic-1.2.6.jar + logback-core-1.2.6.jar + slf4j-api-1.7.36.jar

This doesn't work:

logback-classic-1.3.0.jar + logback-core-1.3.0.jar + slf4j-api-2.0.0.jar +Java 8
