[Mondrian] JDK 1.5 support / JMX

I was wondering about that.  I hate to introduce more conditional logic around jdk version, but maybe that could be an option.

I had added MonitorMXBean to the implements list of MonitorImpl, so we'd also need to somehow account for that.  Possibly by using 2 versions of the interface, one which includes MXBean, and one which would be empty for jdk 1.5.

If we have the build system compile the JMX classes only against java 6+ (like we do with JDBC implementations) would that fix it? We'd have to add the trigger code in UtilCompatible, with a dummy implementation that does nothing in JDK 5 and lower.

I recently made some minor changes in my local fork to expose the
Mondrian monitoring metrics via JMX.  I expect this could be useful for
administrators trying to keep tabs on the current state of their
Mondrian instances.  The changes I made require a feature introduced in
jdk1.6, however, so we won't be able to incorporate it until we stop
supporting 1.5.

So:  how many people are still using 1.5?  What are people's opinions on
how long we should continue to support 1.5?
