+ 	* ''' Version Incompatibilities: ''' Currently, most of Derby's source is built against
Java version 1.3, only code that is inherantly dependant on 1.4 is compiled against javac
version 1.4. However, JMX support is available only on Java versions 5 (1.5) and above. Ant
scripts will have to be modified in this case to support the building of JMX modules. [[BR]]
+ 	* ''' Modules.properties: ''' The modules.properties file uses derby.env.jdk.<tag>={1|2|4}
to identify which modules are supported under which JVM environments. Since JMX requires 5
and above, we need to extend support for 5 and maybe 6 as well. (Not very sure about this)

  	Both Glassfish and Geronimo application servers are built of top of JMX using what is know
as "Inversion of Control" philisophy or the Hollywood style design, which is similar to way
Derby is built. Geronimo uses GBeans to add components to the core server and Glassfish is
also built around the same lines. There are two wasy in which Derby's features can be exposed
from Glassfish and Geronimo:

  	I think for the benifit of most users, option 1 seems to be the better choice. This way,
Derby's developers get more flexibility while instrumentation of Derby GBean can be better
left to Geronimo/Glassfish communities.
