------------------------------------------------------------------
The fact LOGGER.error is used in a try catch Throwable inside a shutdown hook
is a bad idea, in my opinion we should consider using System.err or just invoke
t.printStacktrace().. instead as LOGGER.error may fail and the root cause of
the error will be masked. I will try patching log4j-core to find the root cause
of my exception.
