Description

When running the OSGi tests for LOG4J2-1664, a new java.lang.ClassNotFoundException: org.apache.logging.log4j.core.util.ExecutorServices (for both Felix and Equinox) appeared recently.

Here is the Felix stack trace:

ERROR StatusLogger Failed to preload ExecutorServices class.
 java.lang.ClassNotFoundException: *** Class 'org.apache.logging.log4j.core.util.ExecutorServices' was not found because bundle org.apache.logging.log4j.api [1] does not import 'org.apache.logging.log4j.core.util' even though bundle org.apache.logging.log4j.core [2] does export it. To resolve this issue, add an import for 'org.apache.logging.log4j.core.util' to bundle org.apache.logging.log4j.api [1]. ***
