I've only seen this in development as that's where I redeploy bundles most
actively. Should I change from using the static Logger creation method to
using the OSGi LogService?
I create my logger like so:
private static final Logger LOGGER =
LoggerFactory.getLogger(ContentPoolProvider.class);
and use it like so:
if (LOGGER.isDebugEnabled()) {
LOGGER.debug("List Children [{}] ", parent.getPath());
}
After reloading a few bundles (sometimes more, sometimes less), I'll get
this stacktrace which renders then bundle useless until I restart the
server:
