When only pax-logging-api and DefaultServiceLog are used there is no identification of level in messages. So it is not convenient to read a lot of logs. So I suggest to modify DefaultServiceLog in pax-logging-api to show log level at the beginning of the message. It requires very little change in code.
Could you provide a PR to modify the 3 backends please ?
I think there are no backends in this case. We just have to change org.ops4j.pax.logging.internal.DefaultServiceLog#output to receive and output level. WDYT?
