Regression (3.12) : Cannot debug server chassis (-Ddebug)

[planetf1]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

No debug is enabled by passing -Ddebug or setting LOGGING_LEVEL_ROOT=debug etc - these techniques are essential to debugging non-egeria issues such as kafka client, class loading, jackson parsing errors etc, often with refinements ie:

➜  egeria-3.12-distribution.tar.gz git:(egeria-release-3.12) java -Ddebug -jar  server/server-chassis-spring-3.12.jar| head -20

Expected Behavior

In the 3.11 release & previously, when the -Ddebug flag is passed, or other logging options like -Dlogging.level.root, we get extra info which can be useful to debug spring/jackson./classloader issues ie:

➜  egeria-3.11-distribution.tar.gz git:(egeria-release-3.11) java -Ddebug -jar  server/server-chassis-spring-3.11.jar| head -20

Any Further Information?

Affects maven and gradle builds

[planetf1]

The breakage appears to be caused by slf4J 2.x

The following change restores the logging

-        slf4jVersion = '2.0.3'
+        slf4jVersion = '1.7.36'

Log entries made by egeria work fine with both versions - this would have been clear from testing. However the controllability of spring logging is broken.

Version 1.7.36 of slf4J is the latest 1.x version, and does not show as containing any known security vulnarabilities.

There is some discussion about spring logging breakage with 2.0 -- given we expect a major spring version change for the next version of egeria, I am going to suggest reverting the logging version for now, and we can review once on the new spring boot version - there may be other subtleties with versions of logback etc, so this is the simplest, reasonable, change to get us back to where things were in 3.11
