Thanks for the prompt reply.
I have first tried my custom appender in OSGi environment which gave the
errors above. But I am getting the same issue in non-OSGi environment too.
It seems an issue with custom appender.
AFAIK It is plugin annotation that make the appender visible to log4j2. I
can't find any issue in my log4j2.xml and plugin configuration of the
class. Is there any other places that I need to care about?
Thanks,
Nipuni
