Remko Popma created LOG4J2-1772:
-----------------------------------
Summary: Build for core module stalls between unit tests and
integration tests
Key: LOG4J2-1772
URL: https://issues.apache.org/jira/browse/LOG4J2-1772
Project: Log4j 2
Issue Type: Bug
Components: Core
Reporter: Remko Popma
When building with {{mvn clean install}} there is a mysterious multi-minute
wait after the unit tests for the core module and before the integration tests.
I took a thread dump but could not find the cause, posting it here in case
anyone else has any idea of what may cause this.
