Each log message is accompanied by a log code which is useful in understanding the current state
of the Platform. Log codes are of the form: 'SPXY1234L', where
SP stands for Spring Platform,
XY stands for the subsystem code, 1234 represents the
error number, and L conveys the level of severity of the event being logged.
Below is the list of subsystem codes and their corresponding subsystems:
CC - ConcurrentCN - ControlCO - ConfigDE - DeployerFF - FFDCKB - BootstrapKE - KernelOP - OSGiPM - ProfileSC - ServletWE - Web
The error numbers start from 0000 and typically increase by 1.
There is no upper limit for error numbers.
E - ErrorW - WarnI - Info
Error denotes that there are problems in the Platform, such as incorrect behaviour of
the system. This is the most serious of the log events.
Warn denotes that errors exist, but they are not critical and may be overlooked.
Info provides information about events in the system that may be useful in diagnosing
warnings and errors. Such events are not severe.
