Helber Belmiro commented on LOG4J2-1936:
----------------------------------------
[~jvz] I've found the solution. It's necessary to change the
org.apache.logging.log4j.api bundle to import the
org.apache.logging.log4j.core.async package in it's MANIFEST.MF.
{{Import-Package: org.apache.logging.log4j,org.apache.logging.log4j.mess
age,org.apache.logging.log4j.simple,org.apache.logging.log4j.spi,org.
apache.logging.log4j.status,org.apache.logging.log4j.util,org.osgi.fr
amework;version="[1.6,2)",org.osgi.framework.wiring;version="[1.0,2)"
,sun.reflect;resolution:=optional,org.apache.logging.log4j.core.osgi;
resolution:=optional,org.apache.logging.log4j.core.util;resolution:=o
ptional,*{color:red}org.apache.logging.log4j.core.async;resolution:=optional{color}*}}
It's also necessary to set the system property
"org.osgi.framework.system.packages.extra" to "sun.misc", because without it
the com.lmax.disruptor bundle can't find the sun.misc package.
