Freeman Fang commented on KARAF-1545:
-------------------------------------

Hi,

I'm also a little bit concerned about this change.

IMO the jars in KARAF_HOME/lib  which could get loaded by default should be=
 only those that do very fundamental  karaf bootstrap work, any other libs =
should be installed and  managed as OSGi bundle(including the JDBC driver)

Or for example in KARAF_HOME/lib folder we also have org.apache.servicemix.=
specs.activator.jar since Karaf 2.3.x(used for endorsed specs), this isn't =
added in the current Karaf launch script CLASSPATH, we build a URLClassLoad=
er to load it in org.apache.karaf.main.Main.

> I was trying to configure JDBC fail-over, so I put my mysql driver jar in=
 the KARAF_HOME/lib directory.  I kept getting ClassNotFoundExceptions.  On=
 the advice of someone on IRC, I changed the name to "karaf-mysql-connector=
-java.jar" and it started working.  Why the karaf- prefix requirement?  If =
that's the intended behavior, then please update the README file in the lib=
 directory.  It says:
> "Any jar in this folder will be part of the main classloader used to load=
 Karaf."
