[logback-user] Logback defaulting to debug mode for some third party libraries

[amit shah]

On troubleshooting further I released that hibernate and apache client
libraries use the default logger context created during the initialization
time. This logger context has the root log level set to DEBUG.
We use JNDI as the context selector.

It is strange that the context name is not found at runtime when the
ConnectionManager class (hibernate class -
org.hibernate.jdbc.ConnectionManager) tries to instantiate a logger. Logger
instance creation calls ContextJNDISelector.getLoggerContext() method. This
method does a JNDI lookup but does not find the entry.

I troubleshooted further by spawning a thread in a servlet context listener
to print the JNDI entry (java:comp/env/logback/context-name) every 3
seconds. The logs from the thread indicate that the JNDI entries are always
present.

Any ideas why is contextName is not found in JNDI when queried by
ContextJNDISelector?
